source · [−]

    pub fn tab<I, Error: ParseError<I>>(input: I) -> IResult<I, char, Error> where
        I: Slice<RangeFrom<usize>> + InputIter + InputLength,
        <I as InputIter>::Item: AsChar,

Expand description

Matches a tab character ‘\t’.

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

## Example

    assert_eq!(tab::<_, (_, ErrorKind)>("\tc"), Ok(("c", '\t')));
    assert_eq!(tab::<_, (_, ErrorKind)>("\r\nc"), Err(Err::Error(("\r\nc", ErrorKind::Char))));
    assert_eq!(tab::<_, (_, ErrorKind)>(""), Err(Err::Incomplete(Needed::new(1))));
