According to this answer, #[allow(dead_code)] should work, but it doesn't

fn main() {
    #[allow(dead_code)]
    let x = 0;
}

These are different lints. dead_code refers to unused code at the item level, e.g. imports, functions and types. unused_variables refers to variables that are never accessed.

You can also cover both cases with #[allow(unused)].

The correct is

fn main() {
    #[allow(unused_variables)]
    let x = 0;
}
