Description
When your type implements two traits with the same fn signatures, there's an ambiguity that can be solved by calling Trait::function(instance_of_type). The error is perfect but could add that as suggestion.
For instance ...
error[E0034]: multiple applicable items in scope
--> librustc/ty/sty.rs:1187:13
|
1187 | vid.index()
| ^^^^^ multiple `index` found
|
note: candidate #1 is defined in an impl of the trait `polonius_engine::Atom` for the type `ty::sty::RegionVid`
--> librustc/ty/sty.rs:1174:5
|
1174 | fn index(self) -> usize {
| ^^^^^^^^^^^^^^^^^^^^^^^
note: candidate #2 is defined in an impl of the trait `rustc_data_structures::indexed_vec::Idx` for the type `ty::sty::RegionVid`
--> librustc/ty/sty.rs:1167:1
|
1167 | / newtype_index!(RegionVid
1168 | | {
1169 | | pub idx
1170 | | DEBUG_FORMAT = custom,
1171 | | });

Suggestion: use Idx::index(vid) or Atom::index(vid)
