error[E0106]: missing lifetime specifier

LL | fn g(mut x: impl Iterator<Item = &'_ ()>) -> Option<&'_ ()> { x.next() }

= help: this function's return type contains a borrowed value, but there is no value for it to be borrowed from
help: consider using the `'static` lifetime

error: lifetime may not live long enough

LL | async fn i(mut x: impl Iterator<Item = &'_ ()>) -> Option<&'_ ()> { x.next() }
| -------------- ^^^^^^^^ returning this value requires that `'1` must outlive `'static`
| |
| return type `impl Future<Output = Option<&'static ()>>` contains a lifetime `'1`
error: aborting due to 3 previous errors
