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

--> $DIR/issue-48027.rs:6:6

|
|
LL | impl dyn Bar {}
|
|
| ^^^^^^^ `Bar` cannot be made into an object
|
|
|
|

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>
