//! HNSW-specific segment file layout and merge engine.
//!
//! The generic segment manifest/manager, merge policies, and reader cache
//! shared across index types live in [`crate::vector::index::segment`]
//! (Issue #889); this module keeps only what is HNSW-specific: the merge
//! engine (its I/O is HNSW-graph-typed) and this index type's on-disk file
//! layout descriptor.
