Show HN: Zroar – Serialized Roaring Bitmaps in Zighttps://github.com/manishrjain/zroar
zroar is a ground-up implementation of Roaring Bitmaps data structure in Zig. zroar stores both the keys and (array, bitmap) containers in a single flat byte buffer, making the in-memory representation equal to the on-disk or over-the-network representation, eliminating the serialization/deserialization step entirely. The design was originally aimed at systems which keep their posting lists on disk, but zroar performs faster than CRoaring even for purely in-memory ops, due to CPU cache locality. Against CRoaring 5.0's benchmarking suite (ported to Zig), zroar is faster in 339 out of 360 tests…
