Expand description

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

Complete version: Will return an error if there’s not enough input data, or the whole input if no terminating token is found (a non alphanumerical character).

§Example

fn parser(input: &str) -> IResult<&str, &str> {
    alphanumeric1(input)
}

assert_eq!(parser("21cZ%1"), Ok(("%1", "21cZ")));
assert_eq!(parser("&H2"), Err(Err::Error(Error::new("&H2", ErrorKind::AlphaNumeric))));
assert_eq!(parser(""), Err(Err::Error(Error::new("", ErrorKind::AlphaNumeric))));
