error[E0038]: the trait `ConstParamTy_` cannot be made into an object
--> $DIR/const_param_ty_dyn_compatibility.rs:6:12
|
LL | fn foo(a: &dyn ConstParamTy_) {}
| ^^^^^^^^^^^^^^^^^ `ConstParamTy_` 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>
--> $SRC_DIR/core/src/cmp.rs:LL:COL
|
= note: the trait cannot be made into an object because it uses `Self` as a type parameter
help: consider using an opaque type instead
