Function `tab`

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

Matches a tab character '\t'.

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

Example

# use nom::{Err, error::ErrorKind, IResult, Needed};
# use nom::character::streaming::tab;
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))));
