GPUBindGroupLayoutEntry is accepting an empty dictionary for externalTexture, should accept boolean instead #5249
Description
dictionary GPUBindGroupLayoutEntry {
required GPUIndex32 binding;
required GPUShaderStageFlags visibility;
GPUBufferBindingLayout buffer;
GPUSamplerBindingLayout sampler;
GPUTextureBindingLayout texture;
GPUStorageTextureBindingLayout storageTexture;
GPUExternalTextureBindingLayout externalTexture;
};dictionary GPUExternalTextureBindingLayout {
};This is surprising. It should accept boolean instead and add the dictionary when it's actually needed.
Changing it to boolean won't cause webcompat issue as {} will be automatically coerced to true. Changing it from boolean back to dictionary won't cause webcompat issue either, if we do this:
(boolean or GPUExternalTextureBindingLayout) externalTexture;which is abundant in web platform: https://github.com/search?q=repo%3Aw3c%2Fwebref%20%22(boolean%20or%22&type=code
Dictionary fields with no required member should also accept booleans for consistency.
