Struct Device 

pub struct Device {
    pub name: String,
    pub description: String,
    pub kind: String,
    pub device_type: DeviceType,
    pub device_id: Option<String>,
    pub memory_total: u64,
    pub memory_free: u64,
    pub index: Option<usize>,
    /* private fields */
}

One registered compute device.

Fields

name: String

ggml device name, e.g. “Metal”.

description: String

Human-readable description, e.g. “Apple M4 Max”.

kind: String

Classified vendor kind: “cpu”, “accel”, “metal”, “vulkan”, “cuda”, “rocm”, “sycl”, “gpu”, or “unknown”.

device_type: DeviceType

The CPU/GPU/IGPU/ACCEL axis, orthogonal to Device::kind.

device_id: Option<String>

Stable hardware id when the backend reports one (PCI bus id for PCI devices), or None (e.g. Metal).

memory_total: u64

Reported device memory capacity in bytes, or 0 if unreported.

memory_free: u64

Available device memory in bytes — a snapshot at the time this was queried, or 0 if unreported. Re-query (via devices or crate::Model::device) to refresh it; the value is backend-defined and not comparable across device kinds.

index: Option<usize>

Registry index when this device came from devices. This is useful for display only; pass the Device itself to [ModelOptions] for exact selection. Registry indices are not stable across processes.

Trait Implementations

impl Clone for Device

fn clone(&self) -> Self

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

Formats the value using the given formatter.

impl Eq for Device

impl PartialEq for Device

fn eq(&self, other: &Self) -> bool

Equality operator ==.

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

Inequality operator !=.

impl Send for Device

impl Sync for Device
