Is it possible to be compatible with java based roaringbitmap?

[zuston]

Thanks for your great work in this project.
I want to know is it possible to serialize the bitmap into the bytes in rust side that could be deserialized by java roaringbitmap dependency

Hey @zuston 👋

The serialize_into method serializes a bitmap in a format that is compatible with the Java and the other ones. However, this crate will not generate ranges but bitmaps and lists of integers only.

Thanks for your quick reply @Kerollmops . BTW, which data structure could be compatible with the Roaring64NavigableMap in java side.

Hey @zuston 👋 I don't know which encoder they use. When I read the doc, it seems that they can store up to 2^32 integers, so maybe it's the same encoder as our RoaringTreemap/RoaringBitmap?

Oh thanks. Let me test it and I want to use this crate to replace the roaringc rust binding.
