Struct CommandListRecorder 

pub struct CommandListRecorder { /* private fields */ }

An in-memory recording of a Level Zero command list.

Appends are buffered in order; close seals the list (after which appends are rejected) and reset clears it back to the recording state for reuse — exactly the zeCommandListReset lifecycle.

Implementations

impl CommandListRecorder

pub fn new(ordinal: u32) -> Self

Begin recording a command list targeting queue-group ordinal.

pub fn ordinal(&self) -> u32

The queue-group ordinal this list was created against.

pub fn state(&self) -> CommandListState

Current state of the list.

pub fn len(&self) -> usize

Number of recorded commands.

pub fn is_empty(&self) -> bool

true when no commands have been recorded.

pub fn commands(&self) -> &[RecordedCommand]

The recorded command sequence.

pub fn append_memory_copy( &mut self, dst: u64, src: u64, bytes: u64, ) -> LevelZeroResult<()>

Append a host→device or device→device memory copy.

pub fn append_memory_fill( &mut self, dst: u64, bytes: u64, pattern_len: u32, ) -> LevelZeroResult<()>

Append a memory fill writing a repeating pattern.

pub fn append_launch_kernel( &mut self, kernel: impl Into<String>, groups: GroupCount, signal_event: Option<u32>, ) -> LevelZeroResult<()>

Append a kernel launch with the given grid and optional signal event.

pub fn append_barrier(&mut self, barrier: Barrier) -> LevelZeroResult<()>

Append an execution/event barrier.

pub fn close(&mut self) -> LevelZeroResult<()>

Close the list, sealing it for submission.

pub fn reset(&mut self)

Reset the list back to the recording state, discarding all commands.

pub fn launch_count(&self) -> usize

Number of kernel-launch commands recorded.
