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