Struct AfterCompletionRegistration 

pub struct AfterCompletionRegistration { /* private fields */ }

Opaque non-clone claim for one callback with configured after-completion recurrence.

Implementations

impl AfterCompletionRegistration

pub const fn identity(&self) -> &TimerIdentity

Return the claimed logical identity.

pub fn has_armed_wakeup(&self) -> Result<bool, TimerError>

Return whether this exact claim currently owns an armed provider wake-up.

A callback currently running without an installed successor returns false. This is a volatile observation, not durable scheduling authority or a delivery guarantee.

pub fn ensure_scheduled(&self) -> Result<(), TimerError>

Ensure configured recurrence is armed or retained as the running work’s successor.

pub fn reconcile_schedule( &self, schedule: Option<TimerSchedule>, ) -> Result<(), TimerError>

Reconcile to one exact desired schedule without changing the configured after-completion cadence. None makes a retained declaration inactive after any running work completes or is abandoned; it removes a remove-on-stop declaration and expires this claim when the transition finalizes.

During running work, a winning exact schedule replaces the callback scheduling proposal before validation; explicit invariant failure stops.

pub fn cancel(&self) -> Result<(), TimerError>

Cancel the armed callback or the running work’s successor. Cancellation allocates no callback generation, even at the counter limit.

Consumer work already running is not interrupted. A retained declaration keeps callback authority. A remove-on-stop declaration and this claim expire when cancellation finalizes.

pub fn unregister(self) -> Result<(), TimerError>

Consume the claim and unregister its callback authority.

When called from running work, removal is deferred until that invocation completes normally or its confirmed delivery is abandoned.
