For this purpose, there is the method :meth:`Future.as[T]` which waits until
either the future is completed or its timeout expires, whichever comes first.

normally completed and the answer’s runtime type matches the desired type; if
the future contains an exception or the value cannot be cast to the desired
type, it will throw the exception or a :class:`ClassCastException` (if you want
to get :obj:`None` in the latter case, use :meth:`Future.asSilently[T]`). In
case of a timeout, :obj:`None` is returned.
