error[E0038]: the trait `A` cannot be made into an object
--> $DIR/wf-dyn-incompatible.rs:9:13

LL | let _x: &dyn A;
| ^^^^^^ `A` cannot be made into an object

note: for a trait to be "dyn-compatible" 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>

LL | trait A {

LL | fn foo(&self, _x: &Self);
| ^^^^^ ...because method `foo` references the `Self` type in this parameter
= help: consider moving `foo` to another trait
