Function nom::character::complete::alphanumeric1

pub fn alphanumeric1<T, E: ParseError<T>>(input: T) -> IResult<T, T, E> where
    T: InputTakeAtPosition,
    <T as InputTakeAtPosition>::Item: AsChar, 

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(("&H2", ErrorKind::AlphaNumeric))));
assert_eq!(parser(""), Err(Err::Error(("", ErrorKind::AlphaNumeric))));
