pub fn alphanumeric0<T, E>(input: T) -> Result<(T, T), Err<E>>
where
    E: ParseError<T>,
    T: Input,
    <T as Input>::Item: AsChar,

Recognizes zero or more ASCII numerical and alphabetic characters: 0-9, a-z, A-Z

Example

fn parser(input: &str) -> IResult<&str, &str> {
    alphanumeric0(input)
}

assert_eq!(parser("21cZ%1"), Ok(("%1", "21cZ")));
assert_eq!(parser("&Z21c"), Ok(("&Z21c", "")));
assert_eq!(parser(""), Ok(("", "")));
