Struct Device 

pub struct Device {
    pub device_type: DeviceType,
    pub index: usize,
}

A specific compute device.

Fields

device_type: DeviceType

Device type

index: usize

Device index (for multi-GPU systems)

Implementations

impl Device

pub fn cpu() -> Self

Create a CPU device.

pub fn cuda(index: usize) -> Self

Create a CUDA device with the given index.

pub fn metal() -> Self

Create a Metal device.

pub fn vulkan(index: usize) -> Self

Create a Vulkan device with the given index.

pub fn rocm(index: usize) -> Self

Create a ROCm device with the given index.

pub fn is_cpu(&self) -> bool

Returns true if this is a CPU device.

pub fn is_gpu(&self) -> bool

Returns true if this is a GPU device.

pub fn device_type(&self) -> DeviceType

Returns the device type.

pub fn index(&self) -> usize

Returns the device index.

Trait Implementations

impl Clone for Device

fn clone(&self) -> Device

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Device

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

Formats the value using the given formatter.

impl Default for Device

fn default() -> Self

Returns the “default value” for a type.

impl Display for Device

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

Formats the value using the given formatter.

impl Hash for Device

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Device

fn eq(&self, other: &Device) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
