GPU device information (TRUENO-SPEC-010)

Contains static device properties that don’t change during runtime.

Fields

index: u32

Device index (0-based)

name: String

Device name (e.g., “NVIDIA GeForce RTX 4090”)

vendor: GpuVendor

Vendor identifier

vram_total: u64

Total VRAM in bytes

compute_capability: Option<(u32, u32)>

Compute capability (NVIDIA) or architecture info as (major, minor)

driver_version: Option<String>

Driver version string

pci_bus_id: Option<String>

PCI bus ID (e.g., “0000:01:00.0”)

backend: GpuBackend

wgpu/CUDA backend being used

Implementations

impl GpuDeviceInfo

pub fn new( index: u32, name: impl Into<String>, vendor: GpuVendor, backend: GpuBackend, ) -> Self

Create a new device info with required fields

pub fn with_vram(self, bytes: u64) -> Self

Set VRAM total

pub fn with_compute_capability(self, major: u32, minor: u32) -> Self

Set compute capability

pub fn with_driver_version(self, version: impl Into<String>) -> Self

Set driver version

pub fn with_pci_bus_id(self, bus_id: impl Into<String>) -> Self

Set PCI bus ID

pub fn query() -> Result<Self, MonitorError>

Query device info via wgpu (cross-platform, native only)

On WASM, use async methods with wasm_bindgen_futures.

Errors

Returns error if no GPU is available or query fails.

pub fn query_device(index: u32) -> Result<Self, MonitorError>

Query device info via wgpu for a specific device index (native only)

On WASM, use async methods with wasm_bindgen_futures.

Errors

Returns error if device index is invalid or query fails.

pub fn enumerate() -> Result<Vec<Self>, MonitorError>

Enumerate all available GPU devices (native only)

On WASM, use async methods with wasm_bindgen_futures.

Errors

Returns error if enumeration fails.

pub fn vram_mb(&self) -> u64

Get VRAM in megabytes (convenience method)

pub fn vram_gb(&self) -> f64

Get VRAM in gigabytes (convenience method)

pub fn supports_cuda(&self) -> bool

Check if device supports CUDA (is NVIDIA)
