A type represents the result of a async action.

AsyncActionResult.idle creates the IdleState, indicates the action hasn't started AsyncActionResult.working creates the WorkingState, indicates the action is in progress AsyncActionResult.succeeded creates the SucceededState, indicates the action is completed AsyncActionResult.failed creates the FailedState, indicates the action is failed
