Future Meme Template

Right after calling this function, valid. The function template std::async runs the function f asynchronously (potentially in a separate thread which might be a part of a thread pool) and returns a std::future that will. You can use annotations because annotations have existed since python 3.0, you don't need to import anything from __future__ to use them what you're. Future.

Future & operator =(future &&) noexcept; If the future is the result of a call to std::async that used lazy evaluation, this function returns immediately without waiting. Shared_future share () noexcept; Future & operator =(const future &) = delete; Blocks until the result becomes available.

Valid() == true after the call. This function may block for longer than. An exception is thrown if *this has no shared state or get_future has already been called. 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). Returns a future object associated.

The first part is easy: If the future is the result of a call to async that used lazy evaluation, this function returns immediately without waiting. The behavior is undefined if valid() == false before the call to this function. The class template std::future provides a mechanism to access the result of asynchronous operations: Checks if the future refers to.

An asynchronous operation (created via std::async,. Right after calling this function, valid. The function template std::async runs the function f asynchronously (potentially in a separate thread which might be a part of a thread pool) and returns a std::future that will. You can use annotations because annotations have existed since python 3.0, you don't need to import anything from __future__.
