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>

--> $DIR/coherence-impl-trait-for-trait-object-safe.rs:6:43
|
|
|
|
|
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
|
