1) Default constructor. Constructs an empty
shared_future object that does not refer to a shared state.2) Constructs a
shared_future object, transferring the shared state held by f, if any. After construction, f.valid() is false.3) Constructs a shared future that refers to the same shared state as
f, if any.4) Constructs a
shared_future object from the shared state referred to by other. The resulting shared_future object becomes ready when one of the following happens:
- other and other.get() are both ready. The value or exception from other.get() is stored in the shared state associated with the resulting
shared_futureobject. - other is ready, but other.get() is invalid. An exception of type std::future_error with an error condition of std::future_errc::broken_promise is stored in the shared state associated with the resulting
shared_futureobject.
After this constructor returns, valid() == true and other.valid() == false.
5) Constructs a
shared_future object, transferring the shared state held by f, if any. After construction, f.valid() is false.Parameters
| f | - | another future object to initialize with |
| other | - | A std::experimental::future object to unwrap
