The class template std::future provides a mechanism to access the result of asynchronous operations: An asynchronous operation (performed via std::async, std::packaged_task, or std::promise) can provide a std::future object to the creator of that asynchronous operation.
Understanding the Context
The creator of the asynchronous operation can then use a variety of methods to query, wait for, or extract a value from the ... If the future is the result of a call to std::async that used lazy evaluation, this function returns immediately without waiting. This function may block for longer than timeout_duration due to scheduling or resource contention delays. The standard recommends that a steady clock is used to measure the duration.

Key Insights
The operation behaves as though set_value, set_exception, set_value_at_thread_exit, and set_exception_at_thread_exit acquire a single mutex associated with the promise object while updating the promise object. Calls to this function do not introduce data races with calls to get_future (therefore they need not synchronize with each other). In summary: std::future is an object used in multithreaded programming to receive data or an exception from a different thread; it is one end of a single-use, one-way communication channel between two threads, std::promise object being the other end.
