2 Checks for types that derive `PartialEq` and could implement `Eq`.
5 If a type `T` derives `PartialEq` and all of its members implement `Eq`,
6 then `T` can always implement `Eq`. Implementing `Eq` allows `T` to be used
7 in APIs that require `Eq` types. It also allows structs containing `T` to derive
