Command-queue-group ordinal the compute queue/list were created on.

name: String

Implementations

impl OneApiDevice

pub fn alloc_shared(&self, size: usize) -> Result<*mut c_void, String>

Allocate a host-accessible USM-shared buffer of size bytes, zeroed. Returns the device pointer (also CPU-dereferenceable on integrated / shared-memory Intel GPUs).

pub fn free(&self, ptr: *mut c_void)

Free a USM buffer previously returned by alloc_shared.

pub fn create_command_list(&self) -> Result<CommandListHandle, String>

Create a fresh closed-on-demand command list on the compute group.

pub fn execute_sync(&self, list: CommandListHandle) -> Result<(), String>

Close list, execute it on the compute queue, and block until complete. Serialized across threads (queues need external synchronization).

Trait Implementations

impl Drop for OneApiDevice

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
