error[E0733]: recursion in an async fn requires boxing
  --> $DIR/post-mono-layout-cycle-2.rs:28:5
   |
LL | /     async fn iter<T>(&mut self, iterator: T)

LL | |     where
LL | |         T: IntoIterator<Item = ()>,
   | |___________________________________^

   |           -------------------------------- recursive call here

   = note: a recursive `async fn` call must introduce indirection such as `Box::pin` to avoid an infinitely sized future

error: aborting due to 1 previous error
