Constructs a new shared_future.
1) Default constructor. Constructs an empty shared future, that doesn't refer to a shared state, that is valid() == false.
2) Constructs a shared future that refers to the same shared state, if any, as
other.3-4) Transfers the shared state held by
other to *this. After the construction, other.valid() == false, and this->valid() returns the same value as other.valid() would have returned before the construction.Parameters
| other | - | another future object to initialize with |
