Log crate with notice level

Is there a crate for logging that supports more than 5 levels, esp. a level between info and warning like Unix syslog' notice?

A crate Slog have 6 levels:

pub enum Level {
    Critical,
    Error,
    Warning,
    Info,
    Debug,
    Trace,
}

but i don't know if trace == notice.

casual_loger have 7 levels.

Thanks for the link to the bug report. I hope that gets through. I really want a level above Info. Currently, I use Warning with a prefix to identify Notice messages.
