Struct SuspendDetector 

pub struct SuspendDetector { /* private fields */ }

Independent suspend detector for callers that run on their own timer and can’t rely on the shared checkpoint()/GAP_LOG pair, which is only written by the main tick loop. Two independently-scheduled tokio tasks that both freeze during a host suspend become “due” at roughly the same instant on wake with no ordering guarantee between them — a caller reading GAP_LOG right after wake can race the main loop’s own checkpoint() call and observe no gap yet. A SuspendDetector avoids the race by tracking its own Instant/wall-clock baseline, so it detects the gap from its own frozen timer instead of waiting on another task to record it.

Implementations

impl SuspendDetector

pub fn new() -> Self

pub fn check(&mut self) -> Option<ChronoDuration>

Record a checkpoint on this detector and return the suspend gap (if any) detected since the previous call.

Trait Implementations

impl Default for SuspendDetector

fn default() -> Self

Returns the “default value” for a type.
