error[E0038]: the trait alias `SelfInput` is not dyn compatible
--> $DIR/self-in-generics.rs:8:19
|
LL | pub fn f(_f: &dyn SelfInput) {}
| ^^^^^^^^^ `SelfInput` is not dyn compatible
|
note: for a trait to be dyn compatible it needs to allow building a vtable

--> $DIR/self-in-generics.rs:6:23

LL | pub trait SelfInput = Fn(&mut Self);
| --------- ^^^^^^^^^^^^^
| | |
| | ...because it uses `Self` as a type parameter
| | ...because it uses `Self` as a type parameter
| this trait is not dyn compatible...
help: consider using an opaque type instead

LL - pub fn f(_f: &dyn SelfInput) {}
LL + pub fn f(_f: &impl SelfInput) {}
