operator-(
CompactedArray_ConstIterator<TYPE> const& iterator,
std::ptrdiff_t offset);The returned iterator, it, referencing a CompactedArray array, remains valid as long as 0 <= it - array.begin() <= array.length(). The behavior is undefined unless CompactedArray_ConstIterator() != iterator and 0 <= iterator - array.begin() - offset <= array.length().
