In the library's current state, if I have something like:

#[derive(Redact)]
struct AuthInfo {
    login: String,
    #[redact]
    password: String,
}

fn main() {
    let info = AuthInfo {
        login: "name".to_string(),
        password: "/Jb@`?f.?%!hj2".to_string(),
    };

    println!("{info:#?}");
}

It will output

AuthInfo {
    login: "name",
    password: "/**@`?*.?%!***",
}

Which reveals a good portion of the password. As far as I could find, there was not a way to change this behavior. In my opinion it is pretty much a deal breaker as far as this library goes. I would be willing to submit a PR if needed. Not sure the desired method for that though, like a feature flag, an extra option or what.
