1) Default constructor. Constructs an empty
future
object that does not refer to a shared state.2) Constructs a
future
object, transferring the shared state held by f
, if any. After construction, f.valid() is false.3) Copy constructor is deleted.
future
} cannot be copied.4) Constructs a
future
object from the shared state referred to by other
. The resulting 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
future
object. - 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
future
object.
After this constructor returns, valid() == true and other.valid() == false.
Parameters
f | - | another future object to initialize with |
other | - | A std::experimental::future object to unwrap
