PRIMETIMER: Darla Claire’s ex-roommate leaks FaceTime call where TikToker laughs when Breckie Hill makes fun of FaZe Lacy Darla Claire’s ex-roommate leaks FaceTime call where TikToker laughs when Breckie Hill makes fun of FaZe Lacy Note that std::future references shared state that is not shared with any other asynchronous return objects (as opposed to std::shared_future). The code above might look ugly, but all you have to understand is that the FutureBuilder widget takes two arguments: future and builder, future is just the future you want to use, while builder is a function that takes two parameters and returns a widget. FutureBuilder will run this function before and after the future completes.

Understanding the Context

A std::future<T> is a handle to a result of work which is [potentially] not, yet, computed. You can imagine it as the receipt you get when you ask for work and the receipt is used to get the result back. For example, you may bring a bike to bike store for repair. You get a receipt to get back your bike.

Key Insights

While the work is in progress (the bike being repaired) you can go about other business ... 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> 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 eventually hold the result of that function call.
