pub fn newline<I, Error: ParseError<I>>(input: I) -> IResult<I, char, Error> where
I: Slice<RangeFrom<usize>> + InputIter + InputLength,
<I as InputIter>::Item: AsChar,
Expand description
Matches a newline character ‘\n’.
Streaming version: Will return Err(nom::Err::Incomplete(_))
if there’s not enough input data.
Example
assert_eq!(newline::<_, (_, ErrorKind)>("\nc"), Ok(("c", '\n')));
assert_eq!(newline::<_, (_, ErrorKind)>("\r\nc"), Err(Err::Error(("\r\nc", ErrorKind::Char))));
assert_eq!(newline::<_, (_, ErrorKind)>(""), Err(Err::Incomplete(Needed::new(1))));
