Expand description

A sealed segment with a completed HNSW index.

Fields§

§index: HnswIndex

Built HNSW index (immutable after construction).

§base_id: u32

Base ID offset.

§sq8: Option<(Sq8Codec, Vec<u8>)>

Optional SQ8 quantized vectors for accelerated traversal.

§pq: Option<(PqCodec, Vec<u8>)>

Optional PQ-compressed codes (for HnswPq-configured indexes).

§tier: StorageTier

Storage tier: L0Ram = FP32 in HNSW nodes, L1Nvme = FP32 in mmap file.

§mmap_vectors: Option<MmapVectorSegment>

mmap-backed vector segment for L1 NVMe tier.
