pub fn oct_digit0<T, E>(input: T) -> Result<(T, T), Err<E>>

Complete version: Will return the whole input if no terminating token is found (a non octal digit character).

fn parser(input: &str) -> IResult<&str, &str> {
    oct_digit0(input)
}

assert_eq!(parser("21cZ"), Ok(("cZ", "21")));
assert_eq!(parser("Z21c"), Ok(("Z21c", "")));
assert_eq!(parser(""), Ok(("", "")));
