pub fn new(label: impl Into<String>) -> Self

Create a new, empty command buffer in the Recording state.

pub fn record(&mut self, entry: CommandEntry)

Returns false if the buffer was not in Recording state.

pub fn submit(&mut self) -> Option<Vec<CommandEntry>>

Simulate submission to the GPU queue.

Returns the list of submitted commands (for testing / inspection) and transitions the buffer to Pending.

Returns None if the buffer is not Executable.

pub fn reset(&mut self)

Reset the buffer, clearing all recorded commands.

pub fn begin(&mut self) -> bool

Begin a fresh recording pass after a reset.

Returns false if the buffer was not in Reset state.

pub fn command_count(&self) -> usize

Number of recorded commands.

pub fn state(&self) -> CommandBufferState

Current state of the buffer.

pub fn label(&self) -> &str

Label of this buffer.

pub fn total_estimated_cost(&self) -> f32

Total estimated GPU cost of all recorded commands.
