    pub fn crlf<T, E: ParseError<T>>(input: T) -> IResult<T, T, E> where
        T: Slice<Range<usize>> + Slice<RangeFrom<usize>>,
        T: InputIter,

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))));
