Struct CudaDeviceId 

pub struct CudaDeviceId(/* private fields */);

Provider-qualified identity of a CUDA device ordinal.

A device ID is an opaque CUDA provider value. Use Self::ordinal only when passing the selected ordinal to CUDA APIs. The ordinal is process-visible and may change when CUDA_VISIBLE_DEVICES changes.

Examples

use tenferro_gpu::cuda::CudaDeviceId;

let device = CudaDeviceId::from_ordinal(2);
assert_eq!(device.ordinal(), 2);

Implementations

impl CudaDeviceId

pub const fn from_ordinal(ordinal: u32) -> Self

Construct a device ID from its CUDA ordinal.

Examples

use tenferro_gpu::cuda::CudaDeviceId;

const DEVICE: CudaDeviceId = CudaDeviceId::from_ordinal(0);
assert_eq!(DEVICE.ordinal(), 0);

pub const fn ordinal(self) -> u32

Return the CUDA ordinal represented by this device ID.

Examples

use tenferro_gpu::cuda::CudaDeviceId;

let device = CudaDeviceId::from_ordinal(3);
assert_eq!(device.ordinal(), 3);

Trait Implementations

impl Clone for CudaDeviceId

fn clone(&self) -> CudaDeviceId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CudaDeviceId

impl Debug for CudaDeviceId

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

Formats the value using the given formatter.

impl Eq for CudaDeviceId

impl Hash for CudaDeviceId

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 Ord for CudaDeviceId

fn cmp(&self, other: &CudaDeviceId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for CudaDeviceId

fn eq(&self, other: &CudaDeviceId) -> 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.

impl PartialOrd for CudaDeviceId

fn partial_cmp(&self, other: &CudaDeviceId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
