Implementations

impl TimerOps

pub fn set( delay: Duration, label: impl Into<String>, task: impl Future<Output = ()> + 'static, ) -> TimerId

Schedules a one-shot timer. The task is a single Future, consumed exactly once.

pub fn set_interval<F, Fut>( interval: Duration, label: impl Into<String>, task: F, ) -> TimerId

where F: FnMut() -> Fut + 'static, Fut: Future<Output = ()> + 'static,

Schedules a repeating timer. The task is a closure that produces a fresh Future on each tick.

pub fn clear(id: TimerId)

Clears a previously scheduled timer.

pub fn set_guarded( slot: &'static LocalKey<RefCell<Option<TimerId>>>, delay: Duration, label: impl Into<String>, task: impl Future<Output = ()> + 'static, ) -> bool

Schedule a one-shot timer only if the slot is empty. Returns true when a new timer was scheduled.

pub fn set_guarded_interval<FInit, InitFut, FTick, TickFut>( slot: &'static LocalKey<RefCell<Option<TimerId>>>, init_delay: Duration, init_label: impl Into<String>, init_task: FInit, interval: Duration, interval_label: impl Into<String>, tick_task: FTick, ) -> bool

where FInit: FnOnce() -> InitFut + 'static, InitFut: Future<Output = ()> + 'static, FTick: FnMut() -> TickFut + 'static, TickFut: Future<Output = ()> + 'static,

Schedule a guarded init timer that installs a repeating interval timer. Returns true when a new timer was scheduled. The interval is only installed if the slot still holds the init timer.

pub fn clear_guarded(slot: &'static LocalKey<RefCell<Option<TimerId>>>) -> bool

Clear a guarded timer slot if present. Returns true when a timer was cleared.
