Expand description

Matches a newline character ‘\n’.

§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))));
