pub fn none_of<I, T, Error>(
    list: T,
) -> impl Parser<I, Output = char, Error = Error>
where

Example

assert_eq!(none_of::<_, _, (_, ErrorKind)>("abc")("z"), Ok(("", 'z')));
assert_eq!(none_of::<_, _, (_, ErrorKind)>("ab")("a"), Err(Err::Error(("a", ErrorKind::NoneOf))));
assert_eq!(none_of::<_, _, (_, ErrorKind)>("a")(""), Err(Err::Incomplete(Needed::Unknown)));
