source · 
pub fn newline<I, Error: ParseError<I>>(input: I) -> IResult<I, char, Error>

    I: Slice<RangeFrom<usize>> + InputIter + InputLength,

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))));
