# Function nom::character::streaming::crlf

source · [−]

    pub fn crlf<T, E: ParseError<T>>(input: T) -> IResult<T, T, E> where
        T: Slice<Range<usize>> + Slice<RangeFrom<usize>> + Slice<RangeTo<usize>>,
        T: InputIter,
        T: Compare<&'static str>,

Expand description

Recognizes the string “\r\n”.

Streaming version: Will return `Err(nom::Err::Incomplete(_))` if there’s not enough input data.

## Example

    assert_eq!(crlf::<_, (_, ErrorKind)>("\r\nc"), Ok(("c", "\r\n")));
    assert_eq!(crlf::<_, (_, ErrorKind)>("ab\r\nc"), Err(Err::Error(("ab\r\nc", ErrorKind::CrLf))));
    assert_eq!(crlf::<_, (_, ErrorKind)>(""), Err(Err::Incomplete(Needed::new(2))));
