2026-09-26: NVML-backed source for one device ordinal.

Implementations§

Source§

impl NvmlSource

Source

pub fn open(index: u32) -> Result<Self, NvmlUnavailable>

2026-09-26: Over the system library. Err when NVML is not loadable or has no such device.

Source

pub fn with_fns(fns: NvmlFns, index: u32) -> Result<Self, NvmlUnavailable>

2026-09-26: Over an explicit NVML function table.

Trait Implementations§

Source§

impl DeviceSource for NvmlSource

Source§

fn read(&mut self) -> DeviceReading

2026-09-26: One reading, now. Never fails as a whole: an unreadable field is None.
Source§

fn read_errors(&self) -> u64

2026-09-26: Failed reads so far. A “not supported” or “no permission” answer is not a failure. NvmlSource does not count the NVLink state queries: a link that does not answer is skipped.
