Detailed Description

A handle for a scheduled event.

EventId eid = scheduler.schedule(10_ms, [] { doSomething(); });
eid.cancel(); // cancel 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.
