This change is to help with an attempt to allow the Context type in wgpu to be swappable at runtime. In order to do that, the functions provided by Context and it's associated types need to be object safe. Instead of passing a impl trait that combines both HasRawWindowHandle and HasRawDisplayHandle, we seperate the types into their RawDisplayHandle and RawWindowHandle parts internally to reduce some of the hal implementation code mess.
Change `Instance::as_hal<A>` to simply return an
`Option<&A::Instance>`, rather than passing it to a callback. We're
just borrowing a reference to some `wgpu_hal::Api::Instance` owned by
the `wgpu_core::instance::Instance`, so there's no special scoping or
locking magic required here.
* Use () instead of PhantomData as IdentityManager's Input type.
PhantomData suggests that there's some sort of persuasion required
for lifetime variance inference or other sorts of arcana, but it
doesn't seem to be necessary at all. `()` works just fine.
* Have `prepare_staging_buffer` take a raw hal Device.
This helps the borrow checker understand that we can borrow
`pending_writes`'s encoder and the raw Device at the same time.
* Always free staging buffers.
We must ensure that the staging buffer is not leaked when an error
occurs, so allocate it as late as possible, and free it explicitly when
those fallible operations we can't move it past go awry.
Fixes#2959.
* Some tests for texture and buffer copies.
* Add CHANGELOG.md entry.
Since `wgpu-core`'s public functions are supposed to validate their
parameters, the internal `track` module skips many of Rust's usual
run-time checks in release builds. However, some `wgpu-core` users are
happy to pay the performance cost in exchange for more safety. The
`"strict_asserts"` feature causes `wgpu_core` to perform the same
checks in release builds as it does in debug builds.
* Validate that map_async's range is not negative.
map_async already checks that the range's end is within the bounds of the buffer, so this also ensures the range start is within bounds.
* Add an entry in the changelog.
* Record that the buffer is mapped when its size is zero.
* Avoid internally trying to map a zero-sized buffer if mapped_at_creation is true.
* Add an entry in the changelog.
* Ensure the BufferMapAsyncCallback is always called.
This solves two issues on the Gecko side:
- The callback cleans up after itself (the user data is deleted at the end of the callback), so dropping the callback without calling it is a memory leak. I can't think of a better way to implement this on the C++ side since there can be any number of callback at any time living for an unspecified amount of time.
- This makes it easier to implement the error reporting of the WebGPU spec.
* Update the changelog.
* Make the color attachments `Option`-al in render pipelines, render passes, and render bundles
* vk: `Option`-al color attachments support
* dx12: sparse color_attachments support
* Only non-hole attachments is supported on wasm target and gl backend
* deno_webgpu: `Option`-al color attachments support
* Follow all suggestions
