Struct DeviceId 

pub struct DeviceId {
    pub device_type: DeviceType,
    pub index: u32,
}

A specific device instance: a DeviceType plus an ordinal index.

Fields

device_type: DeviceType

index: u32

Implementations

impl DeviceId

pub fn new(device_type: DeviceType, index: u32) -> DeviceId

Construct a device id.

pub fn cpu() -> DeviceId

The default host device (CPU:0).

pub fn cuda(index: u32) -> DeviceId

A CUDA device by ordinal.

pub fn is_host_accessible(self) -> bool

Whether this device is host-accessible (see DeviceType::is_host_accessible).
