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