| | ^^^^^ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: replace this type to make the impl signature compatible: `Subject<'_, std::collections::hash_map::Keys<'_, K, V>, (), R>` |

| = warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release! |
