Struct ProgressWatchdog 

pub struct ProgressWatchdog<T> { /* private fields */ }

Detects a decode loop that stopped advancing.

Takes the current time from the caller rather than reading the clock, so a test proves the stall behaviour in microseconds instead of sleeping through the timeout.

Implementations

impl<T: Copy + Sub<T, Output = Duration>> ProgressWatchdog<T>

pub const fn new(timeout: Duration, started: T) -> Self

pub fn record_frame(&mut self, now: T)

Record a frame boundary, resetting the stall timer.

pub const fn frames_emitted(&self) -> u64

pub fn check(&self, now: T) -> Result<(), HealthViolation>

Fail if no frame has been recorded within the timeout.
