error[E0053]: method `foo` has an incompatible type for trait
--> $DIR/impl-generic-mismatch-ab.rs:8:32

LL | fn foo<B: Debug>(&self, a: &impl Debug, b: &B) { }
| - ^^^^^^^^^^^ expected type parameter `B`, found type parameter `impl Debug`

| expected type parameter

note: type in trait
--> $DIR/impl-generic-mismatch-ab.rs:4:32

LL | fn foo<A: Debug>(&self, a: &A, b: &impl Debug);
| ^^
= note: expected signature `fn(&(), &B, &impl Debug)`
found signature `fn(&(), &impl Debug, &B)`
= note: a type parameter was expected, but a different one was found; you might be missing a type parameter or trait bound
= note: for more information, visit https://doc.rust-lang.org/book/ch10-02-traits.html#traits-as-parameters
help: change the parameter type to match the trait
