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