Struct wgpu_core::command::CommandBuffer

pub struct CommandBuffer { /* private fields */ }

A buffer of commands to be submitted to the GPU for execution.

Whereas the WebGPU API uses two separate types for command buffers and encoders, this type is a fusion of the two:

• During command recording, this holds a [CommandEncoder] accepting this buffer’s commands. In this state, the CommandBuffer type behaves like a WebGPU GPUCommandEncoder.

• Once command recording is finished by calling Global::command_encoder_finish, no further recording is allowed. The internal [CommandEncoder] is retained solely as a storage pool for the raw command buffers. In this state, the value behaves like a WebGPU GPUCommandBuffer.

• Once a command buffer is submitted to the queue, it is removed from the id registry, and its contents are taken to construct a [BakedCommands], whose contents eventually become the property of the submission queue.
