Roaring64Map
internally uses a std::map
of uint32_t
for the high 32 bits of values, to a 32-bit Roaring bitmap containing the low 32 bits of values with the associated high 32 bits. This means that using roaring_bitmap_contains_range
will only determine whether a specific 32-bit Roaring bitmap contains a given 32-bit range.
To determine whether a 64-bit range is fully present in the Roaring64Map
, we would need to loop over all different high 32 bits of the range, and check the corresponding 32-bit Roaring bitmaps for subranges. See a similar implementation here.
