Скачать или смотреть Why and How we fixed std::thread by std::jthread - Nicolai Josuttis [ C++ on Sea 2020 ]

With C++20 we will have a new basic thread class, std::jthread. It will fix some basic flaws of std::thread, because std::thread was not designed as an easy-to-use RAII type and lacks support for stopping a running thread.

Sounds easy: we only have to pass a parameter to signal cancellation and implement a destructor that performs this request before it joins. But regarding concurrency, nothing is easy in programming. The devil is in the details, especially in C++.

So this is not a talk about jthread. It is a talk about how implementing a pretty simple additional concurrent requirement became a tricky task with many traps. You don't want to do it yourself.
