| LL | fn foo() {} |
| | ^^^ ...because associated function `foo` has no `self` parameter |
| = help: only type `Bar` implements the trait, consider using it directly instead |
| help: consider turning `foo` into a method by giving it a `&self` argument |

| LL | fn foo(&self) {} |

| help: alternatively, consider constraining `foo` so it does not apply to trait objects |
