error[E0038]: the trait `X` cannot be made into an object
--> $DIR/issue-67510-pass.rs:13:23
|
LL | fn _func1<'a>(_x: Box<dyn X<Y<'a>=&'a ()>>) {}
| ^^^^^^^^^^^^^^^^^^^ `X` 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>
--> $DIR/issue-67510-pass.rs:10:10

LL | trait X {
| - this trait cannot be made into an object...
LL | type Y<'a>;
| ^ ...because it contains the generic associated type `Y`
= help: consider moving `Y` to another trait
error: aborting due to previous error
