pub fn newline<I, Error: ParseError<I>>(input: I) -> IResult<I, char, Error> where
I: Slice<RangeFrom<usize>> + InputIter,
<I as InputIter>::Item: AsChar, Expand description
Matches a newline character ‘\n’.
Complete version: Will return an error if there’s not enough input data.
Example
fn parser(input: &str) -> IResult<&str, char> {
newline(input)
}
assert_eq!(parser("\nc"), Ok(("c", '\n')));
assert_eq!(parser("\r\nc"), Err(Err::Error(Error::new("\r\nc", ErrorKind::Char))));
assert_eq!(parser(""), Err(Err::Error(Error::new("", ErrorKind::Char))));
