Struct TimerCell 

pub struct TimerCell { /* private fields */ }

Reactive single-shot timer: projects TimerCore’s fire edge onto a cell so has_fired/value dependents invalidate only on the fire (idempotent).

Implementations

impl TimerCell

pub fn new(ctx: &Context, fire_at: u64) -> Self

pub fn tick(&self, ctx: &Context, now: u64) -> bool

Advance to logical time now; returns the fire edge. On a fire the backing cell flips to true (the PartialEq store-guard makes a repeat tick a no-op, so dependents invalidate exactly once).

pub fn has_fired(&self, ctx: &Context) -> bool

Whether the timer has fired (reactive read).

pub fn value(&self, ctx: &Context) -> Option<()>

None before the fire, Some(()) after (reactive read).

pub fn fired_cell(&self) -> Source<bool>

The backing cell, for dependents that want to subscribe directly.

pub fn next_fire(&self) -> Option<u64>
