steps to reproduce:

add following to Cargo.toml

edition = "2024"
rust-version = "1.85.0"

and compile:

error[E0277]: the trait bound `!: IntoResponse` is not satisfied

             and 121 others
     = note: this error might have been caused by changes to Rust's type-inference algorithm (see issue #48950 <https://github.com/rust-lang/rust/issues/48950> for more information)
     = help: did you intend to use the type `()` here instead?
     = note: required for `{closure@src/lib.rs:1236:34: 1236:36}` to implement `Handler<((),), ()>`
note: required by a bound in `axum::routing::get`

     = note: this error originates in the macro `top_level_handler_fn` (in Nightly builds, run with -Z macro-backtrace for more info)
