vulkano/CHANGELOG_VULKANO.md

Unreleased

• Breaking Major changes have been made to most parts of the graphics pipeline state.
  • Each state category is now provided by a separate type ending in State that lives in its own submodule of pipeline. Some of these were existing types that were renamed.
  • Most of the state-setting methods on GraphicsPipelineBuilder are deprecated. State is now set using a _state method, which is given one of the above state types.
• Breaking DynamicStateMode is replaced with a simple bool.
• Breaking The presence of dynamic state in the pipeline state is now expressed more explicitly with two new types, StateMode and PartialStateMode.
• Breaking The PersistentDescriptorSet::start and SingleLayoutDescSetPool::new functions now return Result.
• Breaking DescriptorWrite now takes an iterator instead of a single item, allowing arrayed descriptors to be written in one operation.
• Breaking Removed the EntryPointAbstract trait, which was unused.
• Breaking ComputeEntryPoint and GraphicsEntryPoint now hold a list of DescriptorRequirements instead of DescriptorSetDesc.
• Breaking Removed union, union_multiple and ensure_compatible_with_shader from DescriptorSetDesc, and union from DescriptorDesc. This is now handled by DescriptorRequirements.
• Breaking DescriptorDesc::ensure_compatibility_with_shader now takes DescriptorRequirements instead of another DescriptorDesc.
• Breaking When the shader's layout specifies a descriptor with runtime array, its upper bound from now on interprets as zero by default(previously it was 1).
• Breaking The DescriptorSet trait now has a resources method, which returns a reference to a DescriptorSetResources object. It no longer has the num_buffers, buffer, num_images and image methods.
• Breaking BufferViewRef is replaced with BufferViewAbstract, similar to the existing ImageViewAbstract.
• Breaking UnsafeDescriptorSet::write takes a DescriptorSetLayout instead of Device.
• Breaking DescriptorWrite is now constructed based on the resources stored instead of the descriptor type. The descriptor type is inferred from the descriptor set layout.
• Breaking Added an Arc to many parameters and return types:
  • Objects implementing BufferAccess, BufferViewAbstract, ImageAccess, ImageViewAbstract or DescriptorSet are now always constructed in an Arc, and parameters that take one of these types require the Arc wrapper.
  • The type parameters of BufferView, ImageView and BufferSlice do not contain this implicit Arc.
  • The types DescriptorSetLayout, PipelineLayout, ComputePipeline, GraphicsPipeline, QueryPool, RenderPass and Framebuffer are also always constructed in an Arc.
• Breaking Framebuffer no longer has a type parameter.
  • This made the FramebufferAbstract trait redundant, and it has been removed.
  • CommandBufferLevel and its nested types no longer have a type parameter either.
  • AttachmentsList is no longer needed and has been removed.
• Breaking The dimensions method has been removed as an inherent method from types that already implement ImageAccess, to avoid confusion between the inherent method and the method of the trait when they have different semantics.
• Breaking Replaced DescriptorDescTy with DescriptorType and made further changes to the members of DescriptorDesc.
• Breaking Added a Pipeline trait to hold methods that are common to all pipeline types.
• Breaking Changes to allow allocating variable descriptor counts:
  • The alloc method of the DescriptorPool trait now has a second parameter to specify the number of descriptors to allocate for the variable count binding. If there is no variable count binding in the layout, this should be 0.
  • The alloc method of UnsafeDescriptorPool now takes an iterator of DescriptorSetAllocateInfo.
• For PersistentDescriptorSet when using a layout with a variable count binding, allocate only the number of descriptors needed instead of always the maximum.
• Descriptor resources are now checked against the shader requirements at the time of a draw/dispatch call, rather than at the time the descriptor set is created. Only the resources that are actually needed in the shader are checked, the other resources in a descriptor set are ignored and don't need to be valid.
• Added a new DescriptorRequirements type, which contains requirements imposed by a shader onto a descriptor and the resources bound to it.
  • DescriptorDesc can be created from DescriptorRequirements with the From trait.
  • DescriptorSetDescs can be created from the requirements with the from_requirement constructor.
  • The descriptor requirements of a pipeline can be queried using a new descriptor_requirements method.
• Added basic support for the khr_push_descriptor extension, with an example of how it's used. The implementation is somewhat limited and some of the details may change in a future update.
• Added support for lots more dynamic state, most of which requires features or extensions to use.
• Added support for discard rectangles, in the pipeline::discard_rectangle module.
• Added support for line rasterization state, in the pipeline::rasterization module.
• Added support for color write enable state, in the pipeline::color_blend module.
• GraphicsPipeline now has methods to return each state object it was created with.
• ash has been updated to 0.33.3, which provides new features and extensions.
• Added CommandBufferState::push_constants to retrieve the set of all push constant bytes that have been set.
• Added check to AutoCommandBufferBuilder to ensure that the push constants that are needed by the pipeline have been set.
• Added android platform to external memory cfgs.
• Fixed two bugs related to the requirements for enabled extensions:
• For required extensions that have been promoted, the promoted version now also fulfills the requirement.
• For features that must be enabled in tandem with extensions (e.g. descriptor_indexing), the requirement only applies to Vulkan 1.2 and above, since these features do not exist on earlier versions and thus cannot be enabled.
• Fix device memory builder not including p_next structures.
• Fix exportable image not created with VkExternalMemoryImageCreateInfo.
• Fix mutable bit not set on exportable image.
• ShaderModule can how handle multiple entry points with the same name but differing execution models. ShaderModule::entry_point will now return None if the entry point with the specified name does not exist or is ambiguous. To disambiguate, use ShaderModule::entry_point_with_execution.
• Added a shaderc-debug cargo feature to Vulkano-shaders, to emit debug information in the generated SPIR-V code.
• Added a type_for_format macro, which returns a Rust type that is suitable for representing a given Format.
• Fixed a bug when using vulkano-shaders macro with multiple shaders in release mode.

Version 0.26.0 (2021-10-2)

• Breaking The draw and draw_indexed commands on AutoCommandBufferBuilder now take parameters to explicitly specify the range of vertices and instances to draw.
• Breaking BufferlessDefinition is removed.
• Breaking The VertexSource trait is removed, and has been replaced with the new VertexBuffersCollection trait, which works analogously to DescriptorSetsCollection. Vertex buffers can now be passed in as a tuple, just like descriptor sets.
• Breaking Removed the vertex definition type parameter from GraphicsPipeline, which is no longer needed with the change above.
• Breaking The ComputePipelineAbstract and GraphicsPipelineAbstract traits are no longer needed and have been removed, with their methods made available on the base ComputePipeline and GraphicsPipeline types.
• Breaking Changes to DescriptorDesc and related changes:
  • The variants of DescriptorDescTy now match those of DescriptorType and Vulkan.
  • The array_count and readonly members are renamed to descriptor_count (to match Vulkan) and mutable (with the opposite sense, to match familiar Rust usage).
  • DescriptorImageDesc is renamed to DescriptorDescImage. The dimensions and arrayed members have been combined into a single ImageViewType value.
  • Removed the arrayed member of the InputAttachment variant as well, as the standard now explicitly disallows arrayed input attachments.
  • The ensure_superset_of method has been split into two, one for shader compatibility and one for binding descriptor sets. The error return types of these methods have been revised.
• Breaking The Cubemap and CubemapArray variants of ImageViewType are renamed to Cube and CubeArray to match Vulkan.
• Breaking Setting state in AutoCommandBufferBuilder is now done via separate commands (e.g. bind_descriptor_sets, bind_vertex_buffers) instead of being provided with dispatch/draw commands. This matches how these commands work in Vulkan.
  • Validity of the state is checked by the dispatch/draw commands.
  • DynamicState is removed; each individual state now has its own command to set it. This includes some states that were not previously included in DynamicState.
• Breaking StateCacher is removed; its task is now partially handled by SyncCommandBufferBuilder.
• Breaking Many traits now require Send + Sync: BufferAccess, ImageAccess, ImageViewAbstract, FramebufferAbstract, AttachmentsList, MemoryPoolAlloc, DescriptorSet, DescriptorPoolAlloc, PrimaryCommandBuffer, SecondaryCommandBuffer, CommandPoolAlloc. This further means that any type parameters of types implementing these traits also require Send + Sync.
• BREAKING DescriptorSetLayout::new() now returns Result<Self, DescriptorSetLayoutError> instead of Result<Self, OomError>`
• BREAKING DescriptorCompatibilityError additional variant VariableCount.
• BREAKING GraphicsPipelineCreationError additional variant PipelineLayoutCreationError.
• BREAKING PipelineLayoutCreationError additional variant SetLayoutError.
• BREAKING FixedSizeDescriptorSetsPool has been replaced by SingleLayoutDescSetPool.
• BREAKING Set builders now return &mut Self instead of Self & methods take values wrapped in an Arc.
• Breaking Changes to Format:
  • Format variants are now all uppercase with underscores. This avoids interpretation problems where the underscore is significant for the meaning.
  • The ty method and the FormatTy enum are removed. They are replaced with the NumericType enum, which concerns itself only with the numeric representation and not with other properties. There are now three type_* methods to retrieve it, for colour, depth and stencil respectively.
  • The planes method now returns a slice containing the equivalent single-plane formats of each plane.
• Breaking The ImageAccess trait no longer has the has_color, has_depth and has_stencil methods. This information can be queried using the aspects or type_* methods of Format.
• Breaking Changes made to DescriptorDescTy to support immutable samplers.
• Breaking DescriptorWrite::combined_image_sampler now takes the sampler in an Option. Use None when the descriptor has immutable samplers.
• Breaking Changes to pipeline layout tweaks:
  • DescriptorSetDesc::tweak is renamed to set_buffer_dynamic, and now takes only a single binding index.
  • DescriptorSetDesc::tweak_multiple is removed.
  • The dynamic buffers parameter of GraphicsPipelineBuilder::with_auto_layout has been replaced with a closure that can be used to make tweaks to the descriptor set layouts as needed.
  • ComputePipeline::new has an additional closure parameter identical to the one described above.
• Breaking AttachmentImage::dimensions() now returns [u32; 3] which includes the layer count.
• Breaking Buffers and Images that have with_exportable_fd use dedicated allocation, thus requiring khr_get_memory_requirements2 and khr_dedicated_allocation on top of already needed khr_external_memory and khr_external_memory_fd.
• Breaking Compare is renamed to CompareOp to match Vulkan.
• Breaking Vulkano-shaders no longer generates a Shader struct, but instead provides load as a standalone function that returns Arc<ShaderModule> directly.
• Breaking Vulkano-shaders no longer generates a function for each entry point. Entry points are now retrieved using the entry_point method of ShaderModule.
• Breaking The shader module is moved to the crate root, and spirv is now a submodule of it.
• Breaking ShaderModule::new is renamed to from_bytes to match the existing from_words.
• Breaking ShaderModule now parses and analyses the shader provided to it on construction, checks whether the shader is compatible with the device, and gathers data such as descriptor sets and input/output interfaces directly from its code. To provide this data yourself as before, and avoid parsing, you can use the _with_data constructors.
• Breaking ComputeEntryPoint and GraphicsEntryPoint are removed, as are the functions on ShaderModule that generate them. Instead, you can look up an entry point using the entry_point method.
• Added support for additional shader types in ShaderStage, ShaderStages and PipelineStages.
• Added export_fd and with_exportable_fd to AttachmentImage and StorageImage as well as mem_size which is needed when using those images with Cuda.
• Vulkano-shaders: added extension/feature checks for more SPIR-V capabilities.
• Added support for surface creation from a CAMetalLayer using VK_EXT_metal_surface.
• Bug fixed. Image layout passed to SubImage is now being respected
• The full Rust code is now generated from vk.xml by autogen directly, instead of using intermediate macros.
• Added storage_buffer() method to BufferUsage.
• Fixed mismatched types on Android.
• Fixed bug in descriptor set validity checking that allowed drawing/dispatching with descriptor sets that didn't match the pipeline.
• Fixed bug where the wrong functions were used for retrieving physical device info.
• Fixed minor bug in retrieving features from the physical device.
• Add BSD platforms to external memory (dma-buf fd) cfgs
• Added support for u8 index buffers with the ext_index_buffer_uint8 extension.
• Descriptor sets now support variable count descriptors.
  • e.g. layout(set = 0, binding = 0) uniform sampler2D textures[];
• Non-breaking Format additions:
  • Formats and their metadata are now auto-generated from vk.xml. This significantly expands the support for YCbCr formats in particular.
  • The compatibility method returns an object that can be used to check the compatibility of two formats, explained here.
  • The components method returns the number of bits in each colour component.
  • The compression method returns the compression scheme as a new enum, CompressionType.
  • The requires_sampler_ycbcr_conversion method returns whether the "sampler YCbCr conversion" must be enabled on an image view and sampler in order to use this format.
  • GraphicsPipelineBuilder now uses Vec instead of SmallVec internally to reduced stack usage.
• Added support for descriptors with immutable samplers.
  • They are included as separate members on the appropriate variants of DescriptorDescTy.
  • Added a set_immutable_samplers method to DescriptorSetDesc, which lets you set the immutable samplers for a descriptor. This can be used together with the closure provided to pipeline constructors.
  • add_image can be used when building a descriptor set, to provide an image to a combined image sampler descriptor that has immutable samplers.
• Updated dependencies:
  • png 0.16 > 0.17
  • time 0.2 > 0.3
• AttachmentImage::current_layer_levels_access() now returns the correct range which solves pipeline barriers only affecting the first layers of of a multi-layer AttachmentImage.
• A new Vulkano-shaders macro option shaders to compile several shaders in a single macro invocation producing generated Rust structs common for all specified shaders without duplications. This feature improves type-safe interoperability between shaders.
• Fixed CommandBufferExecFuture adding the command buffer to queue submission after being flushed.
• Added a spirv module to the main crate, which contains an auto-generated parser for SPIR-V files, and various other utilities that can be used to analyze shaders at runtime.
• DescriptorSetLayout now has variable_descriptor_count which returns the descriptor count in a variable count descriptor if present.
• Additional copy buffer to image checks.
• Add clear_depth_stencil_image to AutoCommandBufferBuilder to clear depth / stencil images.
• AutoCommandBufferBuilder and SyncCommandBufferBuilder now have a state method, which can be used to query the state set by previous "bind" and "set" commands.
• Changed parameters requiring an iterator so that they now take IntoIterator, for more flexibility.
• Removed various custom iterator types in favour of returning impl Iterator.
• Replaced the various dynamic state querying methods of GraphicsPipeline with two: dynamic_state to query a single dynamic state, and dynamic_states to iterate over all of them.

Version 0.25.0 (2021-08-10)

• Breaking Refactoring of PhysicalDevice and related types.
  • The module instance::physical_device is moved to device::physical. Items are exported directly from there.
  • Functions on PhysicalDevice that previously returned a custom iterator type now return impl ExactSizeIterator.
  • PhysicalDevice now has new methods supported_extensions and required_extensions. The equivalent constructors on DeviceExtensions are deprecated, but still present.
• Breaking Renamed Device::loaded_extensions to enabled_extensions, to match the terminology used for enabled_features as well as the Vulkan standard.
• Breaking Renamed Instance::loaded_extensions and loaded_layers to enabled_extensions and enabled_layers respectively.
• Breaking Major reorganisation of the descriptor module. Most importantly, its descriptor_set child is moved to the crate root and everything is placed under there. Full list of module changes:
  • descriptor::descriptor_set::* > descriptor_set.
  • descriptor::descriptor::* > descriptor_set::layout.
    • But ShaderStages* are moved to pipeline::shader.
  • descriptor_set::UnsafeDescriptorSetLayout > descriptor_set::layout::DescriptorSetLayout (renamed).
  • descriptor_set::DescriptorSetDesc > descriptor_set::layout.
  • descriptor_set::{FixedSize*} > descriptor_set::fixed_size_pool.
    • Re-exported descriptor_set::FixedSizeDescriptorSetsPool.
  • descriptor_set::{Persistent*} > descriptor_set::persistent.
    • Re-exported descriptor_set::PersistentDescriptorSet, descriptor_set::PersistentDescriptorSetBuildError, descriptor_set::PersistentDescriptorSetError.
  • descriptor_set::{DescriptorPool*, DescriptorsCount, UnsafeDescriptorSetPool*} > descriptor_set::pool.
  • descriptor_set::{StdDescriptorPool*} > descriptor_set::pool::standard.
    • Re-exported descriptor_set::pool::StdDescriptorPool.
  • descriptor_set::{DescriptorWrite, UnsafeDescriptorSet} > descriptor_set::sys.
  • descriptor_set::collection is now private.
• Breaking Features::superset_of is renamed to is_superset_of.
• Breaking The VertexDefinition trait no longer has AttribsIter and BuffersIter as associated types. It instead returns a VertexInput.
• Breaking The various types for vertex definitions (except BufferlessDefinition) have been replaced with the new BuffersDefinition type, which can handle any number of vertex and instance buffers. Examples of how it's used can be seen in the "instancing" and "teapot" examples.
• Breaking InputRate has been renamed to VertexInputRate to match the Vulkan name. The Instance variant now has a divisor member.
• Breaking DescriptorSetDesc is converted from a trait to a struct. DescriptorSetLayout can take this struct in its constructor, as alternative to the iterator which was already possible previously.
• Breaking PipelineLayout is now built from a list of descriptor set layouts and push constant ranges, like in plain Vulkan. It no longer constructs its own descriptor set layouts internally.
• Breaking PipelineLayoutDescPcRange is renamed to PipelineLayoutPcRange.
• Breaking PipelineLayoutDesc is no longer needed and is removed. Its functionality has been moved to DescriptorSetDesc and PipelineLayoutPcRange. This also applies to ComputeEntryPoint, GraphicsEntryPoint and EntryPointAbstract.
• Breaking PipelineLayout now has a descriptor_set_layouts method which returns a slice of all the layouts, replacing the previous descriptor_set_layout which only returned one at a time.
• Breaking Vulkano is now relaying on features from Rustc >= 1.53.0.
• Breaking The boolean graphics parameter on the bind_descriptor_sets method of SyncCommandBufferBuilder, UnsafeCommandBufferBuilder and StateCacher has been replaced with a new enum PipelineBindPoint.
• Breaking Known physical device properties (VkPhysicalDeviceProperties, VkPhysicalDeviceLimits, VkPhysicalDeviceSparseProperties) are now no longer Option<T>.
  • These properties are available with every vkGetPhysicalDeviceProperties2 call.
  • Add some Default instances to make the auto trait happy.
• Breaking Values that represent a size, offset or index on the device are now represented as DeviceSize (a type alias of u64).
• Breaking Fix in push constant ranges with intersecting stage flags.
• Added support for the ext_vertex_attribute_divisor extension, via the new BuffersDefinition type and the additions to VertexInputRate.
• Added is_superset_of method to DeviceExtensions and InstanceExtensions.
• Examples now enable only the features they need instead of all of them.
• Examples have much smarter device selection logic. In the triangle example this is supplied with comments.
• Errors checking(by unwrapping) in MappedDeviceMemory::read_write.
• Add creation of Semaphores with exportable Linux file descriptor on.
• Add method to export file descriptor corresponding to Semaphore.
• SemaphoreBuilder introduced.
• Add DisplayNative enum variant to ColorSpaceEnum (AMD-specific feature).
• Vulkano-shaders now provides the image format for descriptors, if the shader requires a specific format.
• Vulkano-shaders now uses the spirv_headers crate for some of its types.
• Large allocations now use dedicated allocations which improves memory efficiency.
• Add Clone interface for LayerProperties.
• Fixed detection of storage buffers in SPIR-V so that it works for all SPIR-V versions.
• Added VertexInput type, which contains the binding and attribute descriptions.
• Added a vertex_input method to GraphicsPipelineAbstract, which returns a reference to the vertex input.
• Add support for 8bit uniform storage.
• Added limits check for vertex buffer binding numbers.
• Fixed synchronization bug where pipeline barriers were placed based on the binding of resources instead of the draw/dispatch calls that use them.
• SyncCommandBufferBuilder and UnsafeCommandBufferBuilder accept any IntoIterator where they previously only accepted Iterator.
• Updated ash to 0.33.0, vk.xml to 1.2.185, and ran cargo update to update other dependencies' patch versions.
• Add support for EXTENDED_SRGB_NONLINEAR_EXT color space.
• Better error message for wrong color space value
• Added impl BitOr for debug::MessageType and debug::MessageSeverity and some bit field generators, also turning them into const fn.

Version 0.24.0 (2021-06-20)

• Breaking Vulkano-shaders now checks if the device supports the shader's SPIR-V version, when loading the shader.
• Breaking (but unlikely) Vulkano-shaders now compiles to SPIR-V 1.0 by default. If your shader needs features only available in a higher version, you can specify the target version on the shader! macro with the new vulkan_version: "major.minor" and spirv_version: "major.minor" arguments.
• Breaking Changes to how image sample counts are represented.
  • Instead of an integer, functions with a parameter for number of image samples now take a value of SampleCount, an enum with variants named SampleN, where N is a power-of-two integer. It can be converted to a Vulkan SampleCountFlags, and from an integer with try_from.
  • sample_counts field is originaly represented as u32 type, which is now represented by SampleCounts struct-type which is a boolean collection of supported sample_counts. It can be converted to and from a Vulkan SampleCountFlags.
• Breaking Changes to shader interfaces and pipeline layouts.
  • The module descriptor::pipeline_layout has been renamed to pipeline::layout.
  • The trait ShaderInterfaceDef has been replaced by a simple struct ShaderInterface, and its elements method returns a slice instead of an iterator. This means you no longer need to define a new type for a shader interface. The accompanying type ShaderInterfaceDefEntry has been renamed to ShaderInterfaceEntry to match. The ShaderInterfaceDefMatch trait and EmptyShaderInterfaceDef struct have been removed.
  • The trait PipelineLayoutDesc has also been converted into a struct, with methods descriptor_sets and push_constants which return slices. It is functionally equivalent to the old RuntimePipelineDesc type, which is now merged into it. The traits PipelineLayoutSuperset, PipelineLayoutSetsCompatible and PipelineLayoutPushConstantsCompatible have been integrated into this struct as well. The EmptyPipelineDesc trait has been replaced with an ::empty() constructor.
  • Consequently, functions that took a value of these traits now take a plain ShaderInterface or PipelineLayoutDesc. Types that had a type parameter for it no longer have it, e.g. VertexDefinition, GraphicsEntryPoint, GraphicsEntryPointAbstract, PipelineLayout.
  • Now that PipelineLayout has no more type parameter, the trait PipelineLayoutAbstract is removed. The layout type parameter is also removed from ComputePipeline and GraphicsPipeline.
  • ComputeEntryPoint and GraphicsEntryPoint now take a value specifying the push constants descriptor, instead of having a type parameter. The corresponding associated type on EntryPointAbstract has been removed.
  • The GraphicsEntryPointAbstract trait has been removed. GraphicsPipelineBuilder now takes a GraphicsEntryPoint object directly, and has lifetime parameters for the 5 shader types instead. EntryPointDummy is no longer needed and has been removed.
• Breaking The constructors of Instance now take an additional argument to specify the maximum API version.
• Breaking Vulkano is now built on top of Ash instead of vk-sys.
  • The EntryPoints, InstancePointers and DevicePointers types from vk-sys have been replaced with a new module fns containing EntryFunctions, InstanceFunctions and DeviceFunctions. Rather than containing the functions directly, there is a member for each Vulkan version and extension, which is loaded from Ash.
  • The functions to retrieve the function pointers have been renamed to fns.
  • The TYPE associated constant has been removed from the VulkanObject trait. This is now provided by the Ash Handle trait, which the object returned by internal_object must implement.
• Breaking RawInstanceExtensions and RawDeviceExtensions have been removed. The Instance and Device constructors now take &InstanceExtensions and &DeviceExtensions respectively. The loaded_extensions function returns these reference types as well.
• Breaking The restrictions of each enabled extension and feature are checked when creating an instance or device.
• Breaking Physical device properties are now retrieved through a new properties method, returning a &Properties reference.
  • To allow for the possibility that not every property is known by the physical device, fields in Properties are wrapped by an Option.
  • The previous methods for retrieving properties, name, ty, limits, driver_version, pci_device_id, pci_vendor_id, uuid and extended_properties, have been removed.
  • The api_version method remains, but there is now a semantic difference between it and the version reported by properties: The raw property gives the maximum supported version that the driver itself reports, while the method on PhysicalDevice returns the version a logical device would support if it were created from this physical device (that is, restricted by the instance's max_api_version).
• Breaking ImageAccess trait method try_gpu_lock() now has an additional argument to allow locking the image in an uninitialized state.`
• Breaking The conflicts_buffer and conflicts_image methods on the BufferAccess and ImageAccess traits are removed.
• Breaking Draw and dispatch calls on AutoCommandBufferBuilder no longer have a parameter for dynamic offsets. Instead, they are provided as part of the descriptor sets parameter. They are added to each descriptor set individually using the new offsets method on the DescriptorSet trait. SyncCommandBufferBuilder and StateCacher likewise take dynamic offsets as part of the descriptor set.
• Breaking StencilFaceFlags is renamed to StencilFaces, and its variants are also shortened.
• Breaking DynamicStencilValue now contains a front and a back value.
• Breaking The stencil state commands of SyncCommandBufferBuilder now take a StencilFaces value and a u32 instead of DynamicStencilValue.
• Improve ImageLayout checks to prevent AccessError::ImageNotInitialized from occurring where the image is safe to use uninitialized.
• Added DeviceExtensions::khr_spirv_1_4, which allows SPIR-V 1.4 shaders in Vulkan 1.1.
• Added FunctionPointers::api_version to query the highest supported instance version.
• Added Instance::api_version and Device::api_version to return the actual supported Vulkan version. These may differ between instance and device, and be lower than what FunctionPointers::api_version and PhysicalDevice::api_version return.
• Added Instance::max_api_version, which returns the maximum version that was specified when creating the instance.
• Fixed the issue when creating a buffer with exportable fd on Linux(see to #1545).
• The draw_indirect and draw_indexed_indirect commands on AutoCommandBufferBuilder now check the draw count against the max_draw_indirect_count limit.
• Fixed a few documentation errors.
• It is now possible to construct a graphics pipeline without a fragment shader.
• Added support for all core Vulkan 1.1 and 1.2 device features.
• Updated winit to 0.25.
• Fixed the teapot example on ArchLinux (GTX 1650).
• Added support for the SPIR-V draw parameters capability.
• Added support for the VK_KHR_multiview extension.
• Vulkano-shaders: Added support for MultiView SPIR-V capability.
• Multiview example added showing how to utilize the VK_KHR_multiview extension to render to multiple layers of a framebuffer at once.
• All Vulkan extensions supported by Ash are now provided in InstanceExtensions and DeviceExtensions. This includes all but the very newest extensions; new extensions should be added whenever Ash is updated to a new version.
• Every extension is now documented with a link to its Vulkan page and information about requirements, conflicts, promotion and deprecation.
• InstanceExtensions and DeviceExtensions now have a From implementation that takes an iterator of &CStr. There is also a From implementation for Vec<CString> that performs the reverse conversion.
• All Vulkan features supported by Ash are now provided.
• Implement fmt::Display for DisplayMode.
• Clarify return value is in millihertz for DisplayMode.refresh_rate()
• Reworked some of the internals of SyncCommandBufferBuilder, so that a mutex is no longer needed and resource conflict detection is simplified.
• Features::all and Features::none are now const fn.

Version 0.23.0 (2021-04-10)

• Breaking Changes to command buffers:
  • AutoCommandBuffer and the CommandBuffer trait have been split in two, one for primary and the other for secondary command buffers. AutoCommandBufferBuilder remains one type, but has a type parameter for the level of command buffer it will be creating, and some of its methods are only implemented for builders that create PrimaryAutoCommandBuffer.
  • The Flags enum is renamed to CommandBufferUsage, and is exported from the main command_buffer module. The None variant is renamed to MultipleSubmit.
  • Simplified the number of constructors on AutoCommandBufferBuilder by adding a CommandBufferUsage parameter.
  • Kind has been renamed to CommandBufferLevel, and for secondary command buffers it now contains a single CommandBufferInheritance value.
  • CommandBufferInheritance::occlusion_query and UnsafeCommandBufferBuilder::begin_query now take QueryControlFlags instead of a boolean.
• Breaking The non-default constructors of ImageView have been replaced with a builder, created with ImageView::start(image).
• Breaking Added support for component mapping/swizzling on image views.
  • image::Swizzle is moved and renamed to image::view::ComponentMapping. It now has an is_identity method.
  • A non-default component mapping can now be specified for image views, via the new builder. A ComponentMapping parameter has been added to UnsafeImageView as well.
  • The identity_swizzle method on the ImageViewAbstract trait has been replaced with component_mapping, which returns a ComponentMapping directly.
  • Storage image and input attachment descriptors now check for identity swizzling when being built.
• Breaking Major rearranging of framebuffer and render pass-related types:
  • The framebuffer module is renamed to render_pass.
  • RenderPassDesc is now a struct, not a trait. The methods have been simplified, returning a slice reference to the attachments, subpasses and dependencies.
    • Renamed: AttachmentDescription > AttachmentDesc, PassDescription > SubpassDesc, PassDependencyDescription > SubpassDependencyDesc.
    • EmptySinglePassRenderPassDesc is replaced with the RenderPassDesc::empty constructor, or its Default implementation.
    • The RenderPassCompatible, RenderPassDescClearValues and RenderPassSubpassInterface traits are removed, their functionality is moved to RenderPassDesc.
  • RenderPass takes a concrete RenderPassDesc value for construction, and no longer has a type parameter.
    • The RenderPassAbstract trait is removed.
    • GraphicsPipeline and Framebuffer no longer have a render pass type parameter.
    • GraphicsPipelineAbstract and FramebufferAbstract have trait methods to retrieve the render pass instead.
  • The ordered_passes_renderpass! and single_pass_renderpass! macros are unchanged externally.
• Support for queries:
  • Breaking UnsafeQueryPool, UnsafeQuery and UnsafeQueriesRange have Unsafe removed from their names.
  • Breaking QueriesRange is now represented with a standard Rust Range in its API.
  • Breaking The secondary command buffer constructors that have parameters for queries will check if the corresponding features are enabled, and return a different error type.
  • Removed OcclusionQueriesPool, which was incomplete and never did anything useful.
  • get_results has been added to QueriesRange, to copy query results to the CPU.
  • The following functions have been added to both SyncCommandBufferBuilder and AutoCommandBufferBuilder: begin_query (still unsafe), end_query (safe), write_timestamp (still unsafe), copy_query_pool_results (safe), reset_command_pool (still unsafe).
  • Better documentation of everything in the query module.
  • An example demonstrating occlusion queries.
• Breaking Improved the handling of image aspects a little, with the enum ImageAspect and the struct ImageAspects. UnsafeCommandBufferBuilderImageAspect has been removed.
• Breaking Removed the separate structs for each image format. Now, only the Format enum exists.
  • Traits that no longer make sense in this context have been removed: FormatDesc, the Possible*FormatDesc traits, StrongStorage.
  • In types that had a type parameter for the format type, it has been removed.
  • AcceptsPixels has been converted to Pixel, which is implemented on the pixel type rather than on the format type.
• Breaking shader! will generate descriptor information for all variables declared in the shader module, even if they are not used. This reverts the default behavior from the last release.
  • Breaking Added the exact_entrypoint_interface option to shader! to force vulkano to only generate descriptor information for variables that are used. (the default behavior from the last release)
• Breaking AccessFlagBits is renamed to AccessFlags.
• Breaking Minor refactor of UnsafeBuffer:
  • Replaced the various usage functions with a single usage function, mirroring the change made earlier to UnsafeImage.
  • The SparseLevel::sparse member is removed, and UnsafeBuffer::new takes Option<SparseLevel> instead.
• Breaking Swapchain is now constructed using a builder. Swapchain::start will start building a new blank swapchain. Calling recreate on an existing swapchain will create a builder filled with all the properties of the old swapchain.
• Added two methods to Format: planes to query the number of planes in the format, and aspects to query what aspects an image of this type has.
• The deprecated cause trait function on Vulkano error types is replaced with source.
• Fixed bug in descriptor array layers check when the image is a cubemap.
• Vulkano-shaders: Fixed and refined the generation of the readonly descriptor attribute. It should now correctly mark uniforms and sampled images as read-only, but storage buffers and images only if explicitly marked as readonly in the shader.
• Vulkano-shaders: Added support for StoragePushConstant8 SPIR-V capability.
• Fixed a bug which caused a segfault when extending memory allocation info in DeviceMemoryBuilder

Version 0.22.0 (2021-03-31)

• Breaking Updated all code to Rust 2018 edition.
• Breaking DeviceMemoryBuilder::new() takes in memory_index rather than MemoryType.
• Fixed shader! generated descriptor set layouts for shader modules with multiple entrypoints.
  • Breaking Prefixed shader! generated descriptor set Layout structs with the name of the entrypoint the layout belongs to. For shaders generated from GLSL source, this means Layout has been renamed to MainLayout.
  • Breaking shader! will no longer generate descriptor information for variables that are declared but not used in a shader.
• Breaking shader! now accepts structs in shader interfaces decorated with BufferBlock rather than Block.
• Fixed missing barriers in dispatch calls
  • Breaking shader! no longer marks descriptor sets as readonly as a fallback when it doesn't know
    • Breaking The keyword readonly might need to be added in front of the buffer keyword in GLSL files to get them working again
• Breaking Changes to image types:
  • Image types no longer implement ImageViewAccess.
  • Dimensions is removed. Image constructors now take ImageDimensions.
  • ImageDimensions no longer has the cubemap_compatible member. Instead, several image constructors take ImageCreateFlags which specifies this aspect.
  • Replaced the various functions of UnsafeImage to query format features and usage with two that simply return Formatfeatures and ImageUsage.
• Breaking Changes to image view handling:
  • Created a new image::view module for all image view related things.
  • Introduced a new ImageView type, a safe wrapper around UnsafeImageView.
  • The ImageViewAccess trait is renamed to ImageViewAbstract, some methods added, removed or renamed. ImageView implements this trait.
  • UnsafeImageView no longer holds image usage information, nor does it check for valid usage.
• Breaking UnsafeCommandBuffer and SyncCommandBuffer and their corresponding builders and other related types no longer have a type parameter for the command pool allocation, and no longer keep the command pool alive. Their constructors now take an &UnsafeCommandPoolAlloc. Users must now ensure that the pool allocation outlives the command buffers and their builders (AutoCommandBuffer does this itself).
• Breaking The CommandBuffer trait no longer has the PoolAlloc associated type, and has four new methods: num_buffers, buffer, num_images and image.
• Breaking structures passed to ImmutableBuffer::from_data and CpuAccessibleBuffer::from_data must implement Copy to ensure soundness of these functions
• Replaced deprecated compare_and_swap with compare_exchange.

Version 0.21.0 (2021-03-05)

• Breaking Message::layer_prefix turned to Option to prevent segfaults when Vulkan message didn't provide pMessageIdName value

• Breaking On AutoCommandBufferBuilder and SyncCommandBufferBuilder, the update_buffer method now takes data by reference
• Breaking Made PipelineLayoutDescTweaks public, for use with compute pipelines
• Added support for ImageAspect and YV12/NV12 formats, for use with the UnsafeImage API.
• Added basic VK_KHR_external_memory, VK_KHR_external_memory_fd, and VK_EXT_external_memory_dma_buf support.

• Updated dependencies:
  • crossbeam 0.7 -> 0.8

• Added support and validation for the mutable_format and block_texel_view_compatible image creation flags.
• Added format to the ImageViewBuilder, to choose a different format from the underlying image.

Version 0.20.0 (2020-12-26)

• Breaking The ImmutableImage::from_iter and ImmutableImage::from_buffer can build Mipmaps
• Breaking CpuAccessibleBuffer now uses RwLock from parking_lot.
• Breaking The Kind and SubpassContents types have been moved to the root of the command_buffer module.
• Breaking On AutoCommandBufferBuilder, the methods begin_render_pass and next_subpass now take SubpassContents instead of a boolean value.
• Breaking The CommandBuffer trait now has an additional required method, kind.
• Breaking Update dependency winit 0.22 -> 0.24
• Breaking Added an Option to the ComputePipeline constructor to enable pipeline caching.
• Add support for 8bit storage.
• Some safety checks have been added to execute_commands/execute_commands_from_vec on AutoCommandBufferBuilder, but not everything is checked yet so it's still unsafe to call.
• Added two vulkano-win features raw-window-handle_ and winit_ to be able to use vulkano without winit.
• Added function to create surface from RawWindowHandle.
• Added a properties method to Format.
• Added additional device feature flags for enabling SPIR-V related capabilities.

• Added method build_with_cache to the GraphicsPipelineBuilder that enables pipeline caching.
• Check usage bits on image when creating image view.
• Fixing an assertion panic in the SyncCommandBuffer. If the buffer encountered an error while locking the necessary resources, it would unlock all previously locked resources. Images were unlocked incorrectly and an assert in the image unlock function would panic.
• Added support for including precompiled shaders in vulkano-shaders using the bytes option.
• Added an option for Vulkano-Shaders macro to automatically generate standard traits(Default, PartialEq, etc) implementations for Rust types generated from the Shader types, and to derive these structs with external traits.
• Fixed clear Cubemap and CubemapArray framebuffer attachment dimensions; previously only 1/6th of the layers in each of these image layouts were actually considered by the framebuffer (for clearing and rendering). This seems to have been a result of the difference between Dimensions and ImageDimensions.

Version 0.19.0 (2020-06-01)

• Breaking AutoCommandBufferBuilder methods now take a mutable reference to self instead of taking ownership
• Update smallvec 1.2 -> 1.4

• Added additional checks around image/device compatibility.
• Fixed all warnings as of Rust 1.43.1

• dynamic-local-size compute shader example added showing how to utilize subgroupSize to compute and set shader's local size in run time.
• Fixed Vulkano Shaders bug when compute shader local group layout values bound to specialization constants. Now it is possible to define the layout in form of layout(local_size_x_id = 12, local_size_y_id = 13, local_size_z = 1) in; and then set the values as SpecializationConstants {constant_12: 8, constant_13: 4, ...}.
• Allow applications to access the instance and device pointers
