Enum GpuQuerySource 

#[non_exhaustive]
pub enum GpuQuerySource {
    Dxgi,
    Nvml,
    NvidiaSmi,
}

The backend that produced a GPU memory measurement.

#[non_exhaustive]: more backends (e.g., AMD ROCm SMI, Apple Metal) may be added.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Dxgi

Windows DXGI per-process query (IDXGIAdapter3::QueryVideoMemoryInfo).

Nvml

NVML per-process query (nvmlDeviceGetComputeRunningProcesses).

NvidiaSmi

nvidia-smi subprocess. In ProcessGpuInfo this is the device-wide fallback (the subprocess cannot break the figure down per-process for the calling process). In GpuProcessEntry each row is per-process — one entry per CUDA process from nvidia-smi --query-compute-apps.

Trait Implementations

impl Clone for GpuQuerySource

fn clone(&self) -> GpuQuerySource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GpuQuerySource

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

Formats the value using the given formatter.

impl PartialEq for GpuQuerySource

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