    Interface ZVecHnswRabitqIndexParams

    Configuration parameters for an HNSW-RaBitQ index on a vector field.

    HNSW RaBitQ combines HNSW graph-based search with RaBitQ quantization for improved memory efficiency while maintaining high recall.

    Platform support: Only available on Linux x86_64 with AVX2/AVX-512.
