Example

Run on Compiler Explorer

f: (n: int) = {
    std::this_thread::sleep_for(std::chrono::seconds(n));
    std::cout << "thread (n)$ ended" << std::endl;
}

main: () = {
    v: std::vector<std::jthread> = ();
    v.emplace_back(f, 1);
    v.emplace_back(f, 2);
    v.emplace_back(f, 3);
    l: std::list<std::jthread> = ();

    // copy() would not compile, because std::jthread is noncopyable
    std::move(v.begin(), v.end(), std::back_inserter(l));
    _ = l;
}

Output

thread 1 ended
thread 2 ended
thread 3 ended
