Struct ThrottleMonitor 

pub struct ThrottleMonitor { /* private fields */ }

2026-09-26: Rolling detector over successive counter reads.

Holds the previous read; each observe returns the window between the two. The first call after construction returns None: one read cannot be differenced, and a zero would read as “no throttling” rather than “not known yet”.

Implementations

impl ThrottleMonitor

pub fn new() -> Self

pub fn observe( &mut self, now_ms: u64, counters: ThrottleCounters, ) -> Option<ThrottleWindow>

2026-09-26: Difference counters (read at now_ms) against the previous read.

Returns None on the first read and when now_ms is not after the previous read; in the second case the previous read is kept. A counter that went backwards (a driver reload or GPU reset) still yields a window, with the fraction it feeds None rather than a negative or saturated number.

pub fn transitions(&self) -> usize

2026-09-26: Times thermal_active flipped across the retained history.

Separate from the fraction: a part pinned at full throttle has a high fraction and zero transitions, unlike one that flaps every window.

pub fn samples(&self) -> usize

2026-09-26: Windows retained for transitions, so a caller can tell “0 transitions over 30 windows” from “0 over 1”.
