Description

• Problem: It is not obvious for users to create spriv shader modules when consulting docs of wgpu::ShaderSource::SpirV. The signature of SpirV(Cow<'a, [u32]>) alone doesn't given enough information. And the return type of include_spirv! is also not documented.

• See:

  • https://docs.rs/wgpu/0.12.0/wgpu/enum.ShaderSource.html#variant.SpirV
  • https://docs.rs/wgpu/0.12.0/wgpu/macro.include_spirv.html

• Proposed documents enhancement:

  • Add links of include_spirv! and util::make_spirv
  • Add return type of include_spirv!

Testing

Has built documents and checked added links with the following commands:

 cargo doc --features spirv --open
