set ^ enum → new_set

set_i_xor(VALUE set, VALUE other)
{
    VALUE new_set = rb_obj_dup(set);

    if (rb_obj_is_kind_of(other, rb_cSet)) {

        set_iter(tmp, set_xor_i, (st_data_t)new_set);
    }

    return new_set;
}

Returns a new set containing elements exclusive between the set and the given enumerable object. (set ^ enum) is equivalent to ((set | enum) - (set & enum)).

Example

Set[1, 2] ^ Set[2, 3]                   #=> Set[3, 1]
Set[1, 'b', 'c'] ^ ['b', 'd']           #=> Set["d", 1, "c"]
