std::generator
Member functions | ||||
generator::begin | ||||
promise_type | ||||
Iterator | ||||
/*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.
