template< class T > class shared_future;

The class template std::experimental::shared_future extends std::shared_future with the following operations:

  • an unwrapping constructor from future<shared_future<T>>;
  • a member function is_ready to query whether the associated shared state is ready; and
  • a member function then to attach a continuation to the future.

There is no interoperation between std::experimental::shared_future and std::shared_future.
