| error[E0277]: `<P as Process<'_>>::Item` is not an iterator |
| --> $DIR/issue-22872.rs:20:40 |

| LL | let _: Box<dyn for<'b> Wrap<'b>> = Box::new(Wrapper(process)); |
| | ^^^^^^^^^^^^^^^^^^^^^^^^^^ `<P as Process<'_>>::Item` is not an iterator |
| | |
| = help: the trait `std::iter::Iterator` is not implemented for `<P as Process<'_>>::Item` |
| = note: required because of the requirements on the impl of `for<'b> Wrap<'b>` for `Wrapper<P>` |
| = note: required for the cast to the object type `dyn for<'b> Wrap<'b>` |
| help: consider further restricting the associated type |
| | |
| LL | fn push_process<P>(process: P) where P: Process<'static>, <P as Process<'_>>::Item: std::iter::Iterator { |
