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))));
