Struct tor_rtcompat::scheduler::TaskHandle

pub struct TaskHandle { /* private fields */ }

A handle used to control a TaskSchedule.

When the final handle is dropped, the computation governed by the TaskSchedule should terminate.

Implementations

impl TaskHandle

pub fn fire(&self) -> bool

Trigger this handle’s corresponding schedule now.

Returns true if the schedule still exists, and false otherwise.

pub fn fire_at(&self, instant: Instant) -> bool

Trigger this handle’s corresponding schedule at instant.

Returns true if the schedule still exists, and false otherwise.

pub fn cancel(&self) -> bool

Cancel a pending firing of the handle’s corresponding schedule.

Returns true if the schedule still exists, and false otherwise.

pub fn suspend(&self) -> bool

Suspend execution of the corresponding schedule.

If the schedule is ready now, it will become pending; it won’t become ready again until resume() is called. If the schedule is waiting for a timer, the timer will keep counting, but the schedule won’t become ready until the timer has elapsed and resume() has been called.

Returns true if the schedule still exists, and false otherwise.

pub fn resume(&self) -> bool

Resume execution of the corresponding schedule.

This method undoes the effect of a call to suspend(): the schedule will fire again if it is ready (or when it becomes ready).

This method won’t cause the schedule to fire if it was already cancelled. For that, use the fire() or fire_at()` methods.

Returns true if the schedule still exists, and false otherwise.

Trait Implementations

impl Clone for TaskHandle

fn clone(&self) -> TaskHandle

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
