error[E0038]: the trait `Bar` is not dyn compatible
|
|
--> $DIR/mention-correct-dyn-incompatible-trait.rs:19:24
|
|
|
|
|
LL | let test: &mut dyn Bar = &mut thing;
|
|
| ^^^ `Bar` is not dyn compatible
|
|
|
|
|
note: for a trait to be dyn compatible it needs to allow building a vtable
|
|

--> $DIR/mention-correct-dyn-incompatible-trait.rs:4:8

|
|
|
|
LL | fn foo<T>(&self, val: T);
|
|
| ^^^ ...because method `foo` has generic type parameters
|
|
...
|
|
LL | trait Bar: Foo { }
|
|
| --- this trait is not dyn compatible...
|
|
= help: consider moving `foo` to another trait
|
|
= help: only type `Thing` implements `Bar`; consider using it directly instead.
