Interface GpuBindGroupEntry

Binding number, matching the layout's.

The bound resource: a buffer range, a texture view, or a sampler.

Typed as two constituents though the prose names three, because GpuTextureView and GpuSampler are both opaque object aliases on this surface — naming both would duplicate one union constituent — and it is the matching layout entry, never the handle's shape, that tells WebGPU which kind it received.
