T: Stream,
<T as Stream>::Token: AsChar,👎Deprecated since 0.1.0: Replaced with <code>winnow::character::hex_digit1</code>
Expand description
Recognizes one or more ASCII hexadecimal numerical characters: 0-9, A-F, a-f
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 hexadecimal digit character).
Example
fn parser(input: &str) -> IResult<&str, &str> {
hex_digit1(input)
}
assert_eq!(parser("21cZ"), Ok(("Z", "21c")));
assert_eq!(parser("H2"), Err(ErrMode::Backtrack(Error::new("H2", ErrorKind::HexDigit))));
assert_eq!(parser(""), Err(ErrMode::Backtrack(Error::new("", ErrorKind::HexDigit))));WARNING: Deprecated, replaced with winnow::character::hex_digit1
