pub fn one_of<I, T, Error>(list: T) -> impl Fn(I) where
    Error: ParseError<I>,
    I: Slice<RangeFrom<usize>> + InputIter,
    T: FindToken<<I as InputIter>::Item>,
    <I as InputIter>::Item: AsChar,
    <I as InputIter>::Item: Copy,

Example

assert_eq!(one_of::<_, _, (&str, ErrorKind)>("abc")("b"), Ok(("", 'b')));
assert_eq!(one_of::<_, _, (&str, ErrorKind)>("a")("bc"), Err(Err::Error(("bc", ErrorKind::OneOf))));
assert_eq!(one_of::<_, _, (&str, ErrorKind)>("a")(""), Err(Err::Error(("", ErrorKind::OneOf))));
