Struct SystemDeviceManager 

pub struct SystemDeviceManager { /* private fields */ }

System device manager for querying available hardware devices.

This type enumerates and tracks all compute devices available on the current system (CPU, CUDA GPUs, etc.). For operation-level device selection based on tensor shape and op kind, see crate::device_manager::DeviceManager.

Implementations

impl SystemDeviceManager

pub fn new() -> Self

Create a new system device manager.

This queries the system for available devices, including CUDA GPUs if available via nvidia-smi.

pub fn available_devices(&self) -> &[Device]

Get the list of available devices.

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.

Trait Implementations

impl Clone for SystemDeviceManager

fn clone(&self) -> SystemDeviceManager

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SystemDeviceManager

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SystemDeviceManager

fn default() -> Self

Returns the “default value” for a type.
