warning: to use a constant of type `E` in a pattern, `E` must be annotated with `#[derive(PartialEq, Eq)]`

= 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
= note: see https://doc.rust-lang.org/stable/std/marker/trait.StructuralEq.html for details
= note: `#[warn(indirect_structural_match)]` on by default
error[E0004]: non-exhaustive patterns: `&_` not covered

LL | match &[][..] {
| ^^^^^^^ pattern `&_` not covered

= note: the matched value is of type `&[E]`
help: ensure that all possible cases are being handled by adding a match arm with a wildcard pattern or an explicit pattern as shown
