The behavior is undefined if valid () is false before Oct 23, 2023 · The promise is the "push" end of the promise-future communication channel: the operation that stores a value in the shared state synchronizes-with (as defined in std::memory_order) the successful return from any function that is waiting on the shared state (such as std::future::get). The behavior is undefined if valid () is false before Nov 27, 2023 · future (const future &) = delete; ~future (); future & operator =(const future &) = delete; future & operator =(future &&) noexcept; shared_future <R> share () noexcept; // retrieving the value /* see description */ get (); // functions to check state bool valid () const noexcept; void wait () const; template<class Rep, class Period> Oct 23, 2023 · The promise is the "push" end of the promise-future communication channel: the operation that stores a value in the shared state synchronizes-with (as defined in std::memory_order) the successful return from any function that is waiting on the shared state (such as std::future::get). The creator of the asynchronous operation can then use a variety of methods to query, wait for, or extract a value from the std Feb 22, 2024 · The get member function waits (by calling wait ()) until the shared state is ready, then retrieves the value stored in the shared state (if any).
