error[E0038]: the trait `Bar` is not dyn compatible
--> $DIR/mention-correct-dyn-incompatible-trait.rs:19:15
|
LL | let test: &mut dyn Bar = &mut thing;
| ^^^^^^^^^^^^ `Bar` is not dyn compatible
|
note: for a trait to be dyn compatible it needs to allow building a vtable
for more information, visit <https://doc.rust-lang.org/reference/items/traits.html#dyn-compatibility>
--> $DIR/mention-correct-dyn-incompatible-trait.rs:4:8

LL | fn foo<T>(&self, val: T);

LL | trait Bar: Foo { }

= help: consider moving `foo` to another trait
= help: only type `Thing` implements `Bar`; consider using it directly instead.
