Implementations

impl EventEngine

pub fn new() -> Self

pub fn register_device(&mut self, id: DeviceId, short_name: String)

Register a friendly short name (“GPU0”) used in narration.

pub fn observe( &mut self, device: &DeviceId, sample: &DynamicSample, processes: Option<&[ProcessSample]>, mem_total: Option<u64>, temp_slowdown_c: Option<f32>, ) -> Vec<Event>

Derive this tick’s events.

processes is None when the process list was unobservable — the backend’s process probe failed outright. That is emphatically not the same as Some(&[]), which asserts the device really had no processes: an empty list makes every previously-seen pid look like it exited, and process_events would narrate a fact-grade “python (pid 4521) left GPU0, freeing 21.3 GiB” off a driver hiccup. Fact-grade narration of an event that never happened is the failure mode this project treats as fatal, so the unobservable case gets its own arm: the four process-dependent derivations are skipped, and any inference resting on continuous process observation is reset, because this tick broke that premise. Device-level derivations (throttle, VRAM pressure) are unaffected and keep running.
