error[E0038]: the trait `Foo` cannot be made into an object
--> $DIR/missing-assoc-type.rs:5:16
|
LL | fn bar(x: &dyn Foo) {}
| ^^^ `Foo` 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>
--> $DIR/missing-assoc-type.rs:2:10
|
LL | trait Foo {
| --- this trait cannot be made into an object...
LL | type Bar<T>;
| ^^^ ...because it contains the generic associated type `Bar`
= help: consider moving `Bar` to another trait
error: aborting due to 1 previous error
