Struct DeviceSelection 

pub struct DeviceSelection {
    pub kind: DeviceKind,
    pub device_id: i32,
}

Device selection specification.

Fields

kind: DeviceKind

device_id: i32

Implementations

impl DeviceSelection

pub fn cpu() -> Self

Select CPU device.

pub fn cuda(device_id: i32) -> Self

Select CUDA device by index.

pub fn coreml() -> Self

Select CoreML device.

pub fn directml(device_id: i32) -> Self

Select DirectML device by index.

pub fn auto() -> Self

Auto-select the best available device.

Priority by platform:

• macOS: CoreML > CPU
• Linux: CUDA > CPU
• Windows: DirectML > CPU
• Other: CPU

Feature flags are checked at compile time; if the preferred accelerator was not compiled in, falls back to CPU.

Trait Implementations

impl Clone for DeviceSelection

fn clone(&self) -> DeviceSelection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeviceSelection

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

Formats the value using the given formatter.

impl Display for DeviceSelection

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

Formats the value using the given formatter.

impl From<DeviceSelection> for DeviceType

Convert a high-level DeviceSelection into the low-level crate::gpu::DeviceType used by the ONNX Runtime session builder.

fn from(sel: DeviceSelection) -> Self

Converts to this type from the input type.

impl FromStr for DeviceSelection

Parse from string: "cpu", "cuda", "cuda:0", "cuda:1", "coreml", "directml", "directml:0", "tensorrt", "tensorrt:0", "auto".

Parsing is case-insensitive.

type Err = PiperError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.
