std::jthread (C++)

With C++20 you can use std::jthread (“Cooperatively Interruptible Joining Thread”), which does the stop request and the joining in its destructor.

jthread::~jthread()
{
    if (joinable())     // Not joined/detached yet
    {
        request_stop(); // Inform to stop asap
        join();         // Wait until finished
    }
}
