Enum Device 

pub enum Device {
    Cpu,
    Metal,
    Mlx,
    Ane,
    Cuda,
    Rocm,
    Tpu,
    Gpu,
    Vulkan,
    OpenGl,
    DirectX,
    WebGpu,
}

Target device for graph execution.

Each variant maps to a backend crate gated by a Cargo feature. Use Device::is_available() to check if the feature is enabled.

Variants

Cpu

CPU with SIMD (NEON/AVX) + optional BLAS.

Metal

GPU via Apple Metal (Metal Performance Shaders).

Mlx

Apple MLX framework (unified memory GPU).

Ane

Apple Neural Engine.

Cuda

NVIDIA GPU via native CUDA (cuBLAS, cuDNN).

Rocm

AMD GPU via ROCm/HIP.

Tpu

Google TPU via libtpu’s PJRT plugin (no Python).

Gpu

Portable GPU via wgpu (Metal/Vulkan/DX12/WebGPU).

Vulkan

Vulkan compute shaders.

OpenGl

OpenGL compute shaders (legacy).

DirectX

DirectX 12 compute (Windows).

WebGpu

WebGPU (WASM target).

Implementations

impl Device

pub fn name(self) -> &'static str

Human-readable name (no engine-layer info). is_available / available live in rlx-runtime since they consult the engine’s backend registry — keeping them out of the driver layer preserves the one-way dep direction.

pub fn all() -> &'static [Device]

All variant labels — convenience for callers that want to enumerate without listing every variant manually. Pair with rlx_runtime::available_devices() to filter.

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<(), Error>

Formats the value using the given formatter.

impl Display for Device

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

Formats the value using the given formatter.

impl Hash for Device

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

where __H: Hasher,

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 Copy for Device

impl Eq for Device

impl StructuralPartialEq for Device
