    // Required methods
    fn create_compute_queue(&self) -> Result<Self::Queue>;

Factory for creating hardware queues.

Each device implementation provides a factory that creates queues for that device type.

Required Associated Types

type Queue: HardwareQueue

The queue type produced by this factory.

type Signal: TimelineSignal

The signal type used by queues from this factory.

Required Methods

fn create_compute_queue(&self) -> Result<Self::Queue>

Create a new compute queue.

fn create_copy_queue(&self) -> Result<Option<Self::Queue>>

Create a new copy/DMA queue if supported.

Returns None if the device doesn’t support separate copy queues.

fn create_signal(&self) -> Result<Arc<Self::Signal>>

Create a new timeline signal.

fn device(&self) -> &DeviceSpec

Get the device specification.
