| = warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release! |
| = note: for more information, see issue #62411 <https://github.com/rust-lang/rust/issues/62411> |
| = note: the traits must be derived, manual `impl`s are not sufficient |
