impl TimerControl

pub const fn generation(&self) -> u64

Return the latest allocated callback generation.

pub const fn registration(&self) -> TimerRegistration

Return the current logical registration.

pub fn schedule( &mut self, deadline_ns: u64, ) -> Result<TimerControlAction, TimerControlError>

Schedule a deadline, retaining an already scheduled earlier deadline.

pub fn cancel(&mut self) -> Result<TimerControlAction, TimerControlError>

Cancel this timer, deferring cancellation safely when a callback runs.

pub fn reconcile( &mut self, deadline_ns: u64, ) -> Result<TimerControlAction, TimerControlError>

Reconcile this timer to one authoritative deadline.

pub const fn begin(&mut self, generation: u64) -> bool

Begin the scheduled generation, rejecting stale callbacks.

pub fn complete( &mut self, generation: u64, directive_deadline_ns: Option<u64>, ) -> Result<TimerControlAction, TimerControlError>

Complete the running generation and arbitrate its proposed successor against commands received during execution.
