Source 
pub fn not_line_ending<T, E>(input: T) -> Result<(T, T), Err<E>>
where
    E: ParseError<T>,
    T: Slice<Range<usize>> + Slice<RangeFrom<usize>> + Slice<RangeTo<usize>> + InputIter + InputLength + Compare<&'static str>,
    <T as InputIter>::Item: AsChar,
Available on crate feature mtls only.

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

§Example

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

assert_eq!(parser("ab\r\nc"), Ok(("\r\nc", "ab")));
assert_eq!(parser("ab\nc"), Ok(("\nc", "ab")));
assert_eq!(parser("abc"), Ok(("", "abc")));
assert_eq!(parser(""), Ok(("", "")));
assert_eq!(parser("a\rb\nc"), Err(Err::Error(Error { input: "a\rb\nc", code: ErrorKind::Tag })));
assert_eq!(parser("a\rbc"), Err(Err::Error(Error { input: "a\rbc", code: ErrorKind::Tag })));
