std::generator
/*iterator*/ begin ( ) ;
(since C++23)

Pushes coroutine_ into * active_ stack, then evaluates coroutine_. resume ( ) .

Before invocation of begin() the coroutine_ must refer to a coroutine suspended at its initial suspend point .

Return value

An iterator whose coroutine_ member refers to the same coroutine as coroutine_ does.

Notes

It is an undefined behavior to call begin() more than once on the same generator object.
