@ -27,9 +27,10 @@ Changes to two swapchain bitflag types:
- `SupportedSurfaceTransforms` is renamed to `SurfaceTransforms`.
- `SupportedCompositeAlpha` is renamed to `CompositeAlphas`.
Changes to CPU buffer allocation:
- Replaced `CpuBufferPool` with `CpuBufferAllocator`, which is now marked `!Sync` and no longer has a `T` type parameter. The type parameter was moved to the methods, to allow one allocator to allocate as many types of buffers as needed.
- Merged `CpuBufferPoolChunk` and `CpuBufferPoolSubbuffer` into `CpuSubbuffer`.'
Changes to buffers:
- Merged `CpuAccessibleBuffer`, `DeviceLocalBuffer`, `BufferSlice`, `CpuBufferPoolChunk`, `CpuBufferPoolSubbuffer` into `Subbuffer`.
- Removed `BufferAccess`, `TypedBufferAccess`, `BufferAccessObject`, `BufferInner` and `BufferViewAbstract`.
- Replaced `CpuBufferPool` with `SubbufferAllocator`, which is now marked `!Sync` and no longer has a `T` type parameter. The type parameter was moved to the methods, to allow one allocator to allocate as many types of buffers as needed.
Changes to `DescriptorRequirements`:
- The struct has been split into two levels: the per-binding `DescriptorBindingRequirements`, and the per-descriptor-index `DescriptorRequirements`.
@ -58,6 +59,10 @@ Changes to memory allocation:
- `MemoryRequirements::{size, alignment}` fields have been replaced with a single `layout` field.
- `Suballocator::allocate_unchecked` has been removed.
# Breaking changes
- Changes to CPU buffer allocation:
- - Replaced `CpuBufferPool` with `CpuBufferAllocator`, which is now marked `!Sync` and no longer has a `T` type parameter. The type parameter was moved to the methods, to allow one allocator to allocate as many types of buffers as needed.
### Additions
- Added `CpuBufferAllocatorCreateInfo`.
- Allow waiting on `SwapchainAcquireFuture`.
@ -79,6 +84,7 @@ Changes to memory allocation:
- Added the type alias `NonZeroDeviceSize`.
- Added `VertexBufferDescription` and three new methods to the `Vertex` trait that return it: `per_vertex`, `per_instance` and `per_instance_with_divisor`. This deprecates and replaces `BuffersDefinition`.
- Implemented `From<SampleCount>` for `u32`.
- Added `BufferAllocateInfo`.
### Bugs fixed
- [#2094](https://github.com/vulkano-rs/vulkano/issues/2094): Fixed debug assertion when the first command in a command buffer that uses an image expects it to be in the `Undefined` layout.
