Detailed Description

A scoped handle of scheduled event.

Upon destruction of this handle, the event is canceled automatically. Most commonly, the application keeps a ScopedEventId as a class member field, so that it can cleanup its event when the class instance is destructed.

{
  ScopedEventId eid = scheduler.schedule(10_ms, [] { doSomething(); });
} // eid goes out of scope, canceling the event

Note

Canceling an expired (executed) or canceled event has no effect.

Warning

Canceling an event after the scheduler has been destructed may trigger undefined behavior.
