Module storage 

Vector row storage.

VectorStore persists VectorRow records keyed by (table, row_key) and maintains a per-table HNSW index for ANN search. The MVP ships a [MemoryStore] backend that satisfies the Backend trait without external dependencies; a Noxu-backed implementation lives behind the optional noxu feature in [crate::storage::noxu_backend].

Layout:

• Per [VectorTable] there is one HNSW index, one map of live rows, and one tombstone counter.
• Inserts update both the row map and the index in lockstep.
• Deletes soft-delete the index node and remove the row.

Concurrency: every public method takes the table’s Mutex so the index and row map stay in sync without a more elaborate transaction shape.

Structs

MemoryBackend

In-memory backend. Satisfies Backend without writing to disk; useful for tests and for embedders that want a fully-volatile vector cache.

TableSchema

Per-table schema.

TableStats

Snapshot statistics for a table.

VectorRow

A persisted vector row.

VectorStore

Per-table store front.

Enums

IndexAlgorithm

ANN index algorithm selector.

StoreError

Errors returned by VectorStore.

Traits

Backend

Storage backend trait.

Type Aliases

RowKey

Bucket key: an opaque byte string supplied by the client.

RowVisitor

Callback type used by Backend::for_each_row.
