Module id_map 

Bidirectional binding between HNSW node ids and document ids.

Each HNSW index (keyed by its index key: "{collection}" for the base vector, "{collection}:{field}" for a named one) binds every document id to at most one live node, and every node to one document id. Both directions live behind one type, so no caller can update one side only.

Bindings are grouped per index key rather than flattened into "{index_key}:{node}" strings. A flat string key makes chat a prefix of chat2:* and of the named key chat:field:*, so a prefix match leaks nodes of one index into another. The flat form survives only as the persisted layout (VectorIdMap::to_entries / VectorIdMap::from_entries).

Structs

AttachedVectors

The vectors attached to one document id of one collection.

IndexIdMap

The node ↔ document bindings of one HNSW index.

VectorIdMap

The node ↔ document bindings of every HNSW index, keyed by index key.

Functions

persisted_index_key

The index key of one persisted binding: its composite key minus the ":{node}" suffix. None when the composite key does not end in its own node id.

Type Aliases

PersistedIdEntry

One persisted binding: ("{index_key}:{node}", doc_id, node).
