Struct GpuUtilization 

pub struct GpuUtilization {
    pub util_percent: u8,
    pub encoder_percent: u8,
    pub decoder_percent: u8,
    pub mem_used_mib: u32,
    pub mem_total_mib: u32,
    pub temperature_c: Option<u8>,
}

Per-GPU live utilisation snapshot. Read on every load tick (5 s cadence) by the Phase 2 (2026-05-07) worker_load reporter and folded into the WsGpuLeaseEntry for the wire. NVIDIA values come from NVML; Intel values come from sysfs gt_cur_freq_mhz / gt_max_freq_mhz for a coarse “busy” proxy + mem_info_vram_* for memory; AMD is currently a no-op (returns all zeros) — radeontop / amdsmi integration is the proper fix and is deferred per the brief’s “Phase 1 stand-in for Intel; AMD skipped” guidance.

Fields

util_percent: u8

0..=100 compute / overall GPU busy.

encoder_percent: u8

0..=100 NVENC ASIC busy (encoder pipeline).

decoder_percent: u8

0..=100 NVDEC ASIC busy (decoder pipeline).

mem_used_mib: u32

VRAM in use (MiB).

mem_total_mib: u32

VRAM total (MiB) — duplicated from the static device record so the wire entry is self-contained for the FE bar render.

temperature_c: Option<u8>

Core temperature in °C; None when the platform path doesn’t expose it.

Trait Implementations

impl Clone for GpuUtilization

fn clone(&self) -> GpuUtilization

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GpuUtilization

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

Formats the value using the given formatter.

impl Default for GpuUtilization

fn default() -> GpuUtilization

Returns the “default value” for a type.
