   = note: multiple `impl`s satisfying `String: PartialEq<_>` found in the following crates: `alloc`, `std`:
           - impl PartialEq for String;
           - impl PartialEq<Path> for String;
           - impl PartialEq<PathBuf> for String;
help: try using a fully qualified path to specify the expected types
