Implementations

impl Device

pub fn is_gpu(&self) -> bool

Returns true if this device is a GPU

pub fn is_metal(&self) -> bool

Returns true if this device is Metal GPU

pub fn is_cuda(&self) -> bool

Returns true if this device is CUDA GPU

pub fn is_cpu(&self) -> bool

Returns true if this device is CPU

pub fn device_id(&self) -> Option<usize>

Returns the device ID for GPU devices

pub fn metal_if_available(_device_id: usize) -> Device

pub fn cuda_if_available(_device_id: usize) -> Device

pub fn best_available() -> Device

Get the best available device, preferring CUDA, then Metal, then CPU.

Like Device::cuda_if_available and Device::metal_if_available, this probes trustformers’ own GPU backends directly rather than going through scirs2_core::simd_ops::PlatformCapabilities, whose cuda_available is hardcoded false upstream and whose metal_available requires a scirs2 metal feature that trustformers never enables. Using it here would silently always fall back to Device::CPU, even on CUDA/Metal-capable machines.

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 Copy for Device

impl Debug for Device

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

Formats the value using the given formatter.

impl Default for Device

fn default() -> Device

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Device

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Device

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

Formats the value using the given formatter.

impl Eq for Device

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.

impl Serialize for Device

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
