error[E0038]: the trait alias `BB` is not dyn compatible
|
|
--> $DIR/self-in-const-generics.rs:9:16
|
|
|
|
|
LL | fn foo(x: &dyn BB) {}
|
|
| ^^ `BB` is not dyn compatible
|
|
|
|
|
note: for a trait to be dyn compatible it needs to allow building a vtable
|
|

|
--> $DIR/self-in-const-generics.rs:7:12
|
|
|
|
|
LL | trait BB = Bar<{ 2 + 1 }>;
|
|
| -- ^^^^^^^^^^^^^^ ...because it uses `Self` as a type parameter
|
|
| |
|
|
| this trait is not dyn compatible...
|
|
help: consider using an opaque type instead
|
|
|

LL | fn foo(x: &impl BB) {}
