= warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in Rust 2024 and in a future release in all editions!
= note: for more information, see <https://doc.rust-lang.org/nightly/edition-guide/rust-2024/never-type-fallback.html>
= help: specify the types explicitly
note: in edition 2024, the requirement `!: ImplementedForUnitButNotNever` will fail
