Struct Debouncer 

pub struct Debouncer { /* private fields */ }

Coalesces a burst of filesystem change notifications so a rapid series of edits triggers a single re-index rather than one per event. The clock is injected (now), so the logic is deterministic and unit-testable without real sleeps — the seam the watcher loop drives with Instant::now().

Implementations

impl Debouncer

pub fn new(window: Duration) -> Self

A debouncer that fires once the tree has been quiet for window.

pub fn on_event(&mut self, now: Instant)

Record that a change was observed at now.

pub fn is_pending(&self) -> bool

Whether a change is waiting to be handled.

pub fn is_due(&self, now: Instant) -> bool

Whether a re-index is due at now: a change is pending and the tree has been quiet for at least window since the last event. False when nothing is pending.

pub fn clear(&mut self)

Clear the pending change after a re-index has run.
