Enum TimerCmd 

pub enum TimerCmd {
    Schedule {
        tag: u32,
        delay: Duration,
        handle: HandleId,
    },
    ScheduleCallback {
        tag: u32,
        delay: Duration,
        callback: TimerCallback,
    },
    Cancel {
        tag: u32,
    },
    CancelAll,
}

Command sent from the operator fn (sync) to the timer task (async).

Variants

Schedule

Schedule a timer: after delay, emit handle on the node. If a timer with the same tag is already pending, it is cancelled and the old handle is released.

Fields

tag: u32

delay: Duration

handle: HandleId

ScheduleCallback

Schedule a callback-only timer: after delay, invoke callback. No handle emission — the callback manages state and may call Core::emit itself. Used by operators (debounce, throttle) that need finer control than the emit-on-fire pattern.

Fields

tag: u32

delay: Duration

callback: TimerCallback

Cancel

Cancel a pending timer by tag. The held handle (if any) is released. Callback-only timers have no handle to release.

Fields

tag: u32

CancelAll

Cancel all pending timers and release all held handles.
