5/// Handle to a command buffer on the GPU.
6///
7/// A `CommandBuffer` represents a complete sequence of commands that may be submitted to a command
8/// queue with [`Queue::submit`]. A `CommandBuffer` is obtained by recording a series of commands to
9/// a [`CommandEncoder`] and then calling [`CommandEncoder::finish`].
10///
11/// Corresponds to [WebGPU `GPUCommandBuffer`](https://gpuweb.github.io/gpuweb/#command-buffer).
