5/// Handle to a binding group layout.

7/// A `BindGroupLayout` is a handle to the GPU-side layout of a binding group. It can be used to
8/// create a [`BindGroupDescriptor`] object, which in turn can be used to create a [`BindGroup`]
9/// object with [`Device::create_bind_group`]. A series of `BindGroupLayout`s can also be used to
10/// create a [`PipelineLayoutDescriptor`], which can be used to create a [`PipelineLayout`].
11///
12/// It can be created with [`Device::create_bind_group_layout`].
13///
14/// Corresponds to [WebGPU `GPUBindGroupLayout`](
15/// https://gpuweb.github.io/gpuweb/#gpubindgrouplayout).
