where A: HalApi,

Assign id_in an error with the given label.

Ensure that future attempts to use id_in as a buffer ID will propagate the error, following the WebGPU “contagious invalidity” style.

Firefox uses this function to comply strictly with the WebGPU spec, which requires GPUBufferDescriptor validation to be generated on the Device timeline and leave the newly created GPUBuffer invalid.

Ideally, we would simply let device_create_buffer take care of all of this, but some errors must be detected before we can even construct a wgpu_types::BufferDescriptor to give it. For example, the WebGPU API allows a GPUBufferDescriptor’s usage property to be any WebIDL unsigned long value, but we can’t construct a wgpu_types::BufferUsages value from values with unassigned bits set. This means we must validate usage before we can call device_create_buffer.

When that validation fails, we must arrange for the buffer id to be considered invalid. This method provides the means to do so.
