pub fn crlf<T, E: ParseError<T>>(input: T) -> IResult<T, T, E>
where T: Slice<Range<usize>> + Slice<RangeFrom<usize>> + InputIter + Compare<&'static str>,
Expand description

Recognizes the string “\r\n”.

Complete version: Will return an error if there’s not enough input data.

§Example

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

assert_eq!(parser("\r\nc"), Ok(("c", "\r\n")));
assert_eq!(parser("ab\r\nc"), Err(Err::Error(Error::new("ab\r\nc", ErrorKind::CrLf))));
assert_eq!(parser(""), Err(Err::Error(Error::new("", ErrorKind::CrLf))));
