Sparse bitmap implementation in Erlang or Elixir?

Is anyone aware of an Erlang or Elixir library that provides efficient sparse-bitmap operations (including AND, OR, XOR) along the lines of GitHub - lemire/javaewah: A compressed alternative to the Java BitSet class · GitHub? Or can you suggest alternative approaches to this problem space?

I’m aware of GitHub - hashd/bitmap-elixir: Bitmap implementation in Elixir using binaries and integers. Fast space efficient data structure for lookups · GitHub, but it seems lacking the necessary operations; I’m also not sure that it’s under active current maintenance.

Thanks!

Both of these look potentially on-point. Thank you!
