Yielding Generators

by Kirit Sælensminde

From the article:

We've seen how the promise_type together with the coroutine return type handles the interactions between the caller and the coroutine itself.

Our target is to be able to do something pretty simple:

generator count() {
    std::cout << "Going to yield 1" << std::endl;
    co_yield 1;
    std::cout << "Going to yield 2" << std::endl;
    co_yield 2;
    std::cout << "Going to yield 3" << std::endl;
    co_yield 3;
    std::cout << "count() is done" << std::endl;
}
