Struct DeviceInfo 

pub struct DeviceInfo {
    pub ordinal: usize,
    pub name: String,
    pub compute_capability: (u32, u32),
    pub total_memory_bytes: u64,
    pub memory_kind: MemoryKind,
    pub capabilities: Capabilities,
}

A single device exposed by a backend, in a backend-agnostic shape.

compute_capability is interpreted per backend: (major, minor) for CUDA, the GCN/RDNA arch level for ROCm, the shader-model for Vulkan/ Metal/WebGPU, etc. A value of (0, 0) means “not applicable” (e.g. the CPU reference device).

Fields

ordinal: usize

Backend-local device ordinal (0-based).

name: String

Human-readable device name.

compute_capability: (u32, u32)

(major, minor) capability/shader-model, or (0, 0) if N/A.

total_memory_bytes: u64

Total memory available on the device in bytes.

memory_kind: MemoryKind

Predominant memory kind for buffers on this device.

capabilities: Capabilities

Per-device capability report.

Implementations

impl DeviceInfo

pub fn cpu_reference(total_memory_bytes: u64) -> Self

Build the canonical descriptor for the host CPU reference device.

Trait Implementations

impl Clone for DeviceInfo

fn clone(&self) -> DeviceInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeviceInfo

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

Formats the value using the given formatter.

impl Display for DeviceInfo

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

Formats the value using the given formatter.

impl Eq for DeviceInfo

impl PartialEq for DeviceInfo

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