pub fn default_device(&self) -> &Device

Get the default device.

pub fn set_default_device(&mut self, device: Device) -> Result<(), DeviceError>

Set the default device.

pub fn is_available(&self, device: &Device) -> bool

Check if a device is available.

pub fn get_device( &self, device_type: DeviceType, index: usize, ) -> Option<&Device>

Get a device by type and index.

pub fn count_devices(&self, device_type: DeviceType) -> usize

Count devices of a specific type.

pub fn has_gpu(&self) -> bool

Check if any GPU devices are available.
