- **Breaking** `DescriptorWrite` is renamed to `WriteDescriptorSet` to match Vulkan, and moved into the main `descriptor_set` module.
- **Breaking** The constructors of `WriteDescriptorSet` are no longer unsafe. Added convenience constructors for writing non-arrayed bindings.
- **Breaking** Descriptor sets are no longer constructed using a builder, but with an iterator of `WriteDescriptorSet` items. See in the examples how this is used.
-`PersistentDescriptorSet::start` has been replaced with three constructors, `new`, `new_variable` and `new_with_pool`. Each of these takes an iterator of `WriteDescriptorSet`.
-`SingleLayoutDescSetPool::next` takes an iterator of `WriteDescriptorSet` as well.
- **Breaking** Shader reflection now always generates only the descriptor requirements needed for each given entry point, instead of for all of them. The `exact_entrypoint_interface` argument to the `shader!` macro is removed.
- **Breaking** `Sampler` is now constructed using a builder, using `start` instead of `new`. The shortcut functions `simple_repeat_linear` and `simple_repeat_linear_no_mipmap` are retained, but now return `Result`.
- **Breaking** `MipmapMode` is renamed to `SamplerMipmapMode` to match Vulkan.
- **Breaking** `SamplerAddressMode::ClampToBorder` no longer includes a `BorderColor` value. This is now provided with the new builder.
- **Breaking** The `ImageViewAbstract::can_be_sampled` method is removed, and replaced with `Sampler::can_sample`.
- Added `Filter::Cubic`.
- Added support for filter reduction modes on samplers.
- **Breaking** The spelling `mip_level` is used everywhere as a function and variable name for consistency with Vulkan naming.
- **Breaking** Changes to `UnsafeImage`:
- It is now constructed with a builder.
- It is no longer unsafe to construct, only to use.
- Memory requirements are no longer returned on construction, but retrieved by calling `memory_requirements` on the `UnsafeImage`.
-`format_features` now returns a reference.
-`preinitialized_layout` is replaced by `initial_layout`, which returns an `ImageLayout` value.
- **Breaking** Changes to the `ImageAccess` trait:
- Added a `format_features` method, and removed `supports_blit_source` and `supports_blit_destination`.
-`preinitialized_layout` is replaced by `initial_layout`, which returns an `ImageLayout` value.
-`current_layer_levels_access` was misnamed, and is now named `current_array_layers_access`.
-`current_miplevels_access` is now named `current_mip_levels_access`.
- **Breaking** Changes to `ImageView`:
-`UnsafeImageView` has been merged into `ImageView`.
- Removed `with_` from all the builder functions.
- The `ImageViewAbstract` trait now has `VulkanObject` as a supertrait, and no longer has an `inner` method.
- **Breaking** Changes to `Format`:
-`properties` has been moved to `PhysicalDevice::format_properties`. It now supports the `khr_format_feature_flags2` extension.
-`requires_sampler_ycbcr_conversion` has been renamed to `ycbcr_chroma_sampling` and returns `Option<ChromaSampling>`, where `Some` replaces `true`.
-`size` has been renamed to `block_size`.
-`block_dimensions` has been renamed to `block_extent`.
- The members of the `CompressionType` enum have changed.
- **Breaking** The `BufferViewAbstract` trait now has `VulkanObject` as a supertrait.
- **Breaking** `ExternalMemoryHandleType` has been renamed to `ExternalMemoryHandleTypes`, and the singular name `ExternalMemoryHandleType` has been introduced as an enum.
- **Breaking** `ComponentMapping` and `ComponentSwizzle` have been moved to the `sampler` module.
- Each state category is now provided by a separate type ending in `State` that lives in its own submodule of `graphics`. 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** `ShaderInterfaceEntry` now contains the start `location` and `component`, and specifies its type using a new `ty` member instead of as a format.
- **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** 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** 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 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.
- 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.
-`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`.
- **Breaking** The `draw` and `draw_indexed` commands on `AutoCommandBufferBuilder` now take parameters to explicitly specify the range of vertices and instances to draw.
- **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`.
-`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.
- 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](https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/chap43.html#formats-compatibility-classes).
- 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.
- 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.
- 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.
- **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:
- **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.
- **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** Vulkano is now built on top of [Ash](https://github.com/MaikKlein/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** 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.
- 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.
- The `draw_indirect` and `draw_indexed_indirect` commands on `AutoCommandBufferBuilder` now check the draw count against the `max_draw_indirect_count` limit.
- 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.
-`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`.
-`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.
- **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.
- **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** `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.
- 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
-`BufferlessDefinition` and `BufferlessVertices` now derive `Copy` and `Clone`. This allows `GraphicsPipelineBuilder`s that have not yet defined a vertex buffer type to be cloned.
- 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`.
- 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`](https://doc.rust-lang.org/std/marker/trait.Copy.html) to ensure soundness of these functions
- **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`.
- 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`.
- 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.
- 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`.
- Provides new API to fetch additional information of the Physical Device from the `PhysicalDeviceProperties2KHR` structure whenever it possible. In the current implementation only `subgroupSize` property is fetching. This interface can be extended in the future to obtain more metadata depending on community needs.
-`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, ...}`.
- **Breaking** Added `fullscreen_exclusive` field to `Swapchain` initializers to allow the user to specify how fullscreen exclusivity should be handled.
+ Swapchain methods added: `Swapchain::acquire_fullscreen_exclusive()`, `Swapchain::release_fullscreen_exclusive()`, and `Swapchain::is_fullscreen_exclusive()`
- Update shaderc to 0.6. This again allows to use locally installed libraries which reduces the build-time significantly on Arch/Voidlinux (see https://github.com/google/shaderc-rs/issues/58)
- Compressed texture formats can now be uploaded using `ImmutableImage::from_iter`, `ImmutableImage::from_buffer`, `AutoCommandBuilder::copy_buffer_to_image_dimensions`,
This is an emergency breaking breaking change. It fixes Undefined Behaviour that was preventing the compilation of Vulkano on the latest rust nightlies.
- Update shaderc to 0.5. New shaderc has improved pre-built options for libshaderc that significantly reduce package build time and are appropriate for use in CI
-`QueueFamily::explicitly_supports_tranfers` only returns true if `vk::QUEUE_TRANSFER_BIT` is set instead of also always returning true. Removed `supports_transfers`.
