shared_future( const shared_future& other );
| (2) | (since C++11) |
shared_future( std::future<T>&& other );

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, as other, if there's any.
3-4) Transfers the shared state held by other to *this. After the construction, other->valid() == false, also valid() returns the same value as other.valid() would have returned before the construction.
Parameters
