Function crlf

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

Recognizes the string “\r\n”.

Streaming version: Will return Err(nom::Err::Incomplete(_)) if there’s not enough input data.

Example

assert_eq!(crlf::<_, (_, ErrorKind)>("\r\nc"), Ok(("c", "\r\n")));
assert_eq!(crlf::<_, (_, ErrorKind)>("ab\r\nc"), Err(Err::Error(("ab\r\nc", ErrorKind::CrLf))));
assert_eq!(crlf::<_, (_, ErrorKind)>(""), Err(Err::Incomplete(Needed::new(2))));
