Dchecks:¶

!null().

Parameters:¶

Callback &&callback¶: A function object to be invoked with a ReadyFuture<T> referring to the same shared state as *this. The return value of the callback is ignored.

Warning

If this Future corresponds to a deferred operation, it may be necessary to call Force() directly or indirectly in order to ensure the registered callback is ever actually invoked.
