Async Batch Creation In Background

Oct 28, 2024the 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. Mar 12, 2024an asynchronous operation (created via std::async, std::packaged_task, or std::promise) can provide a std::future object to the creator of that asynchronous operation. Oct 23, 2023the class template std::shared_future provides a mechanism to access the result of asynchronous operations, similar to std::future, except that multiple threads are allowed to wait for.

Apr 29, 2025futures the standard library provides facilities to obtain values that are returned and to catch exceptions that are thrown by asynchronous tasks (i.e. Aug 27, 2021if the future is the result of a call to std::async that used lazy evaluation, this function returns immediately without waiting. Feb 24, 2025the execution control library provides a framework for managing asynchronous execution on generic execution resources.

It specifies the launch policy for a task executed by the std::async function. Oct 23, 2023the class template std::promise provides a facility to store a value or an exception that is later acquired asynchronously via a std::future object created by the std::promise object. Feb 10, 2025the class template std::packaged_task wraps any callable target (function, lambda expression, bind expression, or another function object) so that it can be invoked asynchronously.
