Function `newline`

fn newline<I, Error: ParseError<I>>(input: I) -> crate::internal::IResult<I, char, Error>
where
    I: Input,
    <I as Input>::Item: AsChar

Matches a newline character '\n'.

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

Example

# use nom::{Err, error::{Error, ErrorKind}, IResult, Needed};
# use nom::character::complete::newline;
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))));
