+error[E0038]: the trait `NotObjectSafe` cannot be made into an object
+  --> $DIR/coherence-impl-trait-for-trait-object-safe.rs:7:24

+LL | impl NotObjectSafe for dyn NotObjectSafe { }
+   |                        ^^^^^^^^^^^^^^^^^ `NotObjectSafe` 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>

+LL | trait NotObjectSafe { fn eq(&self, other: Self); }
+   |       -------------                       ^^^^ ...because method `eq` references the `Self` type in this parameter
+   |       |
+   |       this trait cannot be made into an object...
+   = help: consider moving `eq` to another trait

+error: aborting due to previous error
