Function winnow::bytes::any

pub fn any<I, E: ParseError<I>>(input: I) -> IResult<I, <I as Stream>::Token, E>where
    I: StreamIsPartial + Stream,

Matches one token

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

Partial version: Will return Err(winnow::error::ErrMode::Incomplete(_)) if there’s not enough input data.

Example

fn parser(input: &str) -> IResult<&str, char> {
    any.parse_next(input)
}

assert_eq!(parser("abc"), Ok(("bc",'a')));
assert_eq!(parser(""), Err(ErrMode::Backtrack(Error::new("", ErrorKind::Token))));

assert_eq!(any::<_, Error<_>>.parse_next(Partial::new("abc")), Ok((Partial::new("bc"),'a')));
assert_eq!(any::<_, Error<_>>.parse_next(Partial::new("")), Err(ErrMode::Incomplete(Needed::new(1))));
