There was a problem hiding this comment.
I checked, and it seems that the rest of the code would handle this fine.

Document `FunctionType` better. Use `FunctionCtx` name key methods where appropriate in the WGSL and HLSL backends.

Description
After
cargo upgrade-ing wgpu-core from 0.12.0 to 0.12.2, and wgpu-hal from 0.12.0 to 0.12.4, a Metal surface with usage flagsTextureUsages::RENDER_ATTACHMENT | TextureUsages::COPY_DSTcould not be configured anymore (macOS 11.6.2) due to a validation mismatch. This PR adds theCOPY_DSTflag to Metal's surface capabilities so validation now passes for this particular usage flag. See "Discussion" below.Testing
The simplest way to test is to add a
wgpu::TextureUsages::COPY_DSTusage flag to hello_triangle example's surface configuration. Prior to this change (and given you're on macOS), you'll get a panicError in Surface::configure: requested usage is not supported. This change fixes the panic.Discussion
I see there's a TODO for possibly exposing more flags, but I'm not knowledgeable enough to add them without discussing first. For example, I feel
DEPTH_STENCIL_WRITEwould also work? I'm happy to test out any additional changes and update the PR.
