| error[E0038]: the trait `Bar` cannot be made into an object |

| LL | impl dyn Bar {} |

| note: for a trait to be "object safe" it needs to allow building a vtable to allow the call to be resolvable dynamically; for more information visit <https://doc.rust-lang.org/reference/items/traits.html#object-safety> |

| = note: cannot satisfy `_: Bar` |
| = note: associated constants cannot be accessed directly on a `trait`, they can only be accessed through a specific `impl` |
