1 error[E0038]: the trait `Foo` cannot be made into an object
2 --> $DIR/object-safety-err-ret.rs:17:16
4 LL | fn use_dyn(v: &dyn Foo) {
5 | ^^^^^^^ `Foo` cannot be made into an object
7 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>

11 | --- this trait cannot be made into an object...
12 LL | fn test(&self) -> [u8; bar::<Self>()];
13 | ^^^^^^^^^^^^^^^^^^^ ...because method `test` references the `Self` type in its return type
14 = help: consider moving `test` to another trait
