std::generator::begin(3)

✨ NAME ✨

Hii bestie 💖 this is the std::generator::begin page from the C++ Standard Library manual, and it's giving “iterator entrance era” 🎀✨

🌀 Synopsis 🌀

/*iterator*/ begin();  (since C++23)

Okay so begin() pushes coroutine_ into *active_ stack, then evaluates coroutine_.resume(). Slay 💅

Before you invoke begin(), coroutine_ must refer to a coroutine that is suspended at its initial suspend point. No cap. 🦋

🎁 Return value 🎁

You get an iterator whose coroutine_ member refers to the same coroutine as coroutine_ does. Iconic. 🫶

💅 Notes 💅

Calling begin() more than once on the same generator object is undefined behavior. Periodt. Do not do it, bestie 😭💀
