error[E0038]: the trait `ConstParamTy_` is not dyn compatible
--> $DIR/const_param_ty_dyn_compatibility.rs:6:16
|
LL | fn foo(a: &dyn ConstParamTy_) {}
| ^^^^^^^^^^^^^ `ConstParamTy_` 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>
--> $SRC_DIR/core/src/cmp.rs:LL:COL
|
= note: the trait is not dyn compatible because it uses `Self` as a type parameter
help: consider using an opaque type instead
