Struct LoopWatchdogCore 

pub struct LoopWatchdogCore { /* private fields */ }

Deterministic state machine underlying LoopWatchdog.

Times are monotonic durations from any caller-chosen epoch. A continuous stall is reported once, and gaps over 60 seconds are treated as system sleep.

Implementations

impl LoopWatchdogCore

pub fn new(now: Duration) -> Self

Create a watchdog core whose last successful render-loop tick was now.

pub const fn tick(&mut self, now: Duration)

Record progress by the render loop at monotonic time now.

pub fn set_phase(&mut self, phase: impl Into<Str>)

Set the label attached to a subsequently detected stall.

pub fn check(&mut self, now: Duration) -> Option<StallReport>

Check for a newly detected stall at monotonic time now.

Returns one report after 250 ms without a tick. Further checks stay silent until Self::tick records progress. Gaps over 60 seconds are suppressed.

impl Debug for LoopWatchdogCore

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

Formats the value using the given formatter.
