error: the trait `X` cannot be made into an object
--> $DIR/issue-50781.rs:6:8
|
LL | fn foo(&self) where Self: Trait;
| ^^^
|
= warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release!
= note: for more information, see issue #51443 <https://github.com/rust-lang/rust/issues/51443>
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>

LL | trait X {
| - this trait cannot be made into an object...
LL | fn foo(&self) where Self: Trait;
| ^^^ ...because method `foo` references the `Self` type in its `where` clause
= help: consider moving `foo` to another trait
note: the lint level is defined here
