Vector search primitives shared by Origin, Lite, and WASM: HNSW + Vamana indexes, scalar / SIMD distance kernels, the quantization codec frontier (SQ8, PQ, IVF-PQ, OPQ, RaBitQ, BBQ, Ternary BitNet 1.58, Binary), the VectorCollection runtime with mmap NVMe segments and background builder, and the cost-model planner inputs (target_recall, oversample, ef_search, query_dim, meta_token_budget, quantization).

This crate has no platform-required cargo features for v0.1.0 — SIMD kernels are gated by #[cfg(target_arch)] and dispatch happens at runtime. The optional acorn-baseline feature retains the old ACORN-1 filtered-traversal heuristic for benchmarking against NaviX; not for production use.

HNSW + Vamana indexes, scalar / SIMD distance, NaviX filtered traversal

Vector search core: HNSW (in-memory hierarchical) and Vamana / DiskANN (SSD-resident, billion-scale). Includes NaviX adaptive-local filtered traversal, SIEVE workload subindices, MetaEmbed multivec + PLAID, and the cost-model planner inputs.

Status

Pre-1.0. APIs may change between minor versions until 1.0. See the workspace README.md for the full project overview and the GitHub release notes for per-version changes.
