Esteban Küber d136b3108d Add more context to fall-through "const pattern of non-structural type" error ... Point at types that need to be marked with `#[derive(PartialEq)]`. We use a visitor to look at a type that isn't structural, looking for all ADTs that don't derive `PartialEq`. These can either be manual `impl PartialEq`s or no `impl` at all, so we differentiate between those two cases to provide more context to the user. We also only point at types and impls from the local crate, otherwise show only a note. ``` error: constant of non-structural type `&[B]` in a pattern --> $DIR/issue-61188-match-slice-forbidden-without-eq.rs:15:9 | LL | struct B(i32); | -------- must be annotated with `#[derive(PartialEq)]` to be usable in patterns LL | LL | const A: &[B] = &[]; | ------------- constant defined here ...
