Defined in header <experimental/shared_future>
template< class T > class shared_future;
(1) (concurrency TS)
template< class T > class shared_future<T&>;
(2) (concurrency TS)
template<>          class shared_future<void>;
(3) (concurrency TS)

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.

Getting the result
returns the result
