~future();
(since C++11)

Releases any shared state. This means

  • if the return object or provider holds the last reference to its shared state, the shared state is destroyed; and
  • the return object or provider gives up its reference to its shared state; and
  • these actions will not block for the shared state to become ready, except that it may block if all of the following are true: the shared state was created by a call to std::async, the shared state is not yet ready, and this was the last reference to the shared state.
(since C++14)
