def verify_duplicates(duplicates, uniques):
    """Verify that a set of intersections had expected duplicates.

    .. note::

       This is a helper used only by :func:`generic_intersect`.

    Args:
        duplicates (List[~bezier.hazmat.intersection_helpers.Intersection]):
            List of intersections corresponding to duplicates that were
            filtered out.
        uniques (List[~bezier.hazmat.intersection_helpers.Intersection]): List
            of "final" intersections with duplicates filtered out.

    Raises:
        ValueError: If the ``uniques`` are not actually all unique.
        ValueError: If one of the ``duplicates`` does not correspond to
            an intersection in ``uniques``.
        ValueError: If a duplicate occurs only once but does not have
            exactly one of ``s`` and ``t`` equal to ``0.0``.
        ValueError: If a duplicate occurs three times but does not have
            exactly both ``s == t == 0.0``.
        ValueError: If a duplicate occurs a number other than one or three
            times.
