Enum AcceleratorKind 

pub enum AcceleratorKind {
    Cpu,
    Cuda,
    Metal,
    Vulkan,
    Rocm,
}

Hardware-acceleration backend the engine adapter is built and running with. Reflects compile-time GGML feature flags. Pure CPU builds (no cuda / metal / vulkan / rocm features) report Cpu. A build with support but where n_gpu_layers == 0 also effectively uses CPU at runtime — see AcceleratorInfo::gpu_layers.

New variants may be added in future patch releases (NPU, etc.); older subscribers should treat unknown variants as Cpu (the fallback that’s always safe).

Variants

Cpu

Built without any GPU/accelerator support.

Cuda

Built with CUDA — NVIDIA GPU offload available.

Metal

Built with Metal — Apple GPU offload available.

Vulkan

Built with Vulkan — cross-vendor GPU offload available.

Rocm

Built with HIP/ROCm — AMD GPU offload available.

Implementations

impl AcceleratorKind

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

Stable wire-form name: "cpu", "cuda", "metal", "vulkan", "rocm". Used in admin status frames and inferdctl doctor.

Trait Implementations

impl Clone for AcceleratorKind

fn clone(&self) -> AcceleratorKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AcceleratorKind

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

Formats the value using the given formatter.

impl Default for AcceleratorKind

fn default() -> AcceleratorKind

Returns the “default value” for a type.

impl PartialEq for AcceleratorKind

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