set_i_replace(VALUE set, VALUE other)
{
    rb_check_frozen(set);

    if (rb_obj_is_kind_of(other, rb_cSet)) {

        set_table_clear(RSET_TABLE(set));
        set_merge_enum_into(set, other);

    return set;
}

Replaces the contents of the set with the contents of the given enumerable object and returns self.

Example

set = Set[1, 'c', :s]             #=> Set[1, "c", :s]
set.replace([1, 2])               #=> Set[1, 2]
set                               #=> Set[1, 2]
