Enumeration Type Documentation

strong

Whether to store or discard a task's return value in task wrappers such as FutureTask or RunOnceTask.

strong

Result from Dispatcher::RunTask. Reports the state of the task when it finished running.

Enumerator
kActive	The task is still posted to the dispatcher.
kDeregistered	The task was removed from the dispatcher by another thread.
kCompleted	The task finished running.
