velesdb-core 1.14.2

//! HNSW (Hierarchical Navigable Small World) index implementation.
//!
//! This module provides high-performance approximate nearest neighbor search
//! based on the HNSW algorithm.
//!
//! # Native Implementation (v1.0+)
//!
//! `VelesDB` uses a custom native HNSW implementation that is:
//! - **1.2x faster search** than external libraries
//! - **1.07x faster parallel insert**
//! - **~99% recall parity** with no accuracy loss
//!
//! # Module Organization
//!
//! - `params`: Index parameters and search quality profiles
//! - `native`: Core HNSW graph with SIMD distance calculations
//! - `index`: Main `HnswIndex` API
