Example

# use nom::{Err, error::ErrorKind};
# use nom::character::complete::one_of;
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))));
