error[E0038]: the trait `DynIncompatible` cannot be made into an object
--> $DIR/coherence-impl-trait-for-trait-dyn-compatible.rs:7:26
|
LL | impl DynIncompatible for dyn DynIncompatible { }
| ^^^^^^^^^^^^^^^^^^^ `DynIncompatible` 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>
--> $DIR/coherence-impl-trait-for-trait-dyn-compatible.rs:6:45
|
LL | trait DynIncompatible { 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[E0046]: not all trait items implemented, missing: `eq`
--> $DIR/coherence-impl-trait-for-trait-dyn-compatible.rs:7:1
|
LL | trait DynIncompatible { fn eq(&self, other: Self); }
| -------------------------- `eq` from trait
LL | impl DynIncompatible for dyn DynIncompatible { }
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ missing `eq` in implementation
