C++20 Concurrency: <stop_token>

A simple way to handle cancellation of asynchronous tasks

In a previous article, I talked about using std::jthread as a simpler and safer way to create multi-threaded C++ programs using C++20. However, I did not discuss the benefits of using the C++20 <stop_token> library header alongside std::jthread for simple cancellation of coroutines and asynchronous tasks.

What is the <stop_token> header used for?

This header contains a few useful components, including std::stop_token…
