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`
= help: consider adding a `where <P as Process<'_>>::Item: std::iter::Iterator` bound
= 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>`
error: aborting due to previous error
