dan sinclair 45ff7a8c4a Remove extra work from `is_reserved`
Currently the `is_reserved` method in the WGSL parser uses the
`operator==` on the token to check the reserved words. This ends up
re-doing a bunch of work as it checks the token type, then gets the
`string_view` or `string` from the variant, then compares.

This CL adds a precondition that the token is an identifier (which is
true in the only case we call this method) and then extracts the string
from the token once and uses that for all the comparisons.

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the work-in-progress WebGPU standard. More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL. Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.

Dawn provides several WebGPU building blocks:

  • WebGPU C/C++ headers that applications and other building blocks use.
    • The webgpu.h version that Dawn implements.
    • A C++ wrapper for the webgpu.h.
  • A "native" implementation of WebGPU using platforms' GPU APIs: D3D12, Metal, Vulkan and OpenGL. See per API support for more details.
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
  • Tint is a compiler for the WebGPU Shader Language (WGSL) that can be used in standalone to convert shaders from and to WGSL.
