Function winnow::character::alphanumeric1

pub fn alphanumeric1<I, E: ParseError<I>>(
    input: I
) -> IResult<I, <I as Stream>::Slice, E>where
    I: StreamIsPartial + Stream,
    <I as Stream>::Token: AsChar,

Recognizes one or more ASCII numerical and alphabetic characters: 0-9, a-z, A-Z

Complete version: Will return an error if there’s not enough input data, or the whole input if no terminating token is found (a non alphanumerical character).

Partial version: Will return Err(winnow::error::ErrMode::Incomplete(_)) if there’s not enough input data, or if no terminating token is found (a non alphanumerical character).

Example

fn parser(input: &str) -> IResult<&str, &str> {
    alphanumeric1(input)
}

assert_eq!(parser("21cZ%1"), Ok(("%1", "21cZ")));
assert_eq!(parser("&H2"), Err(ErrMode::Backtrack(Error::new("&H2", ErrorKind::Slice))));
assert_eq!(parser(""), Err(ErrMode::Backtrack(Error::new("", ErrorKind::Slice))));

assert_eq!(alphanumeric1::<_, Error<_>>(Partial::new("21cZ%1")), Ok((Partial::new("%1"), "21cZ")));
assert_eq!(alphanumeric1::<_, Error<_>>(Partial::new("&H2")), Err(ErrMode::Backtrack(Error::new(Partial::new("&H2"), ErrorKind::Slice))));
assert_eq!(alphanumeric1::<_, Error<_>>(Partial::new("")), Err(ErrMode::Incomplete(Needed::new(1))));
