| * Creates a [Set] containing the elements of this [Iterable]. |
| * The set may contain fewer elements than the iterable, if the iterable |
| * contains an element more than once, or it contains one or more elements |
| * that are equal. The order of the elements in the set is not guaranteed to |
| * be the same as for the iterable. |
| * @description Checks that the returned [Set] contains all elements of [this]. |
