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

LL | t

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: required for `&T` to implement `CoerceUnsized<&dyn Bar>`
= note: required by cast to type `&dyn Bar`
