Struct VectorStore 

pub struct VectorStore { /* private fields */ }

In-memory vector index for fast cosine similarity search.

Loads all embeddings from the Embeddings galaxy into memory on first access. Supports incremental updates (add/remove vectors without full rebuild).

Implementations

impl VectorStore

pub fn new() -> Self

Create a new empty vector store.

pub fn load(&mut self, store: &MemoryStore) -> Result<()>

Load all embeddings from the LMDB Embeddings galaxy into memory.

This scans the Embeddings galaxy and loads all stored embedding vectors. Must be called before search if vectors were stored directly via MemoryStore::put_embedding without going through add.

pub fn add(&mut self, memory_id: Uuid, galaxy: Galaxy, embedding: Vec<f32>)

Add a vector to the index.

pub fn remove(&mut self, memory_id: Uuid) -> bool

Remove a vector from the index.

pub fn len(&self) -> usize

Get the number of indexed vectors.

pub fn is_empty(&self) -> bool

Check if the index is empty.

pub const fn is_loaded(&self) -> bool

Whether the index has been loaded from LMDB.

pub fn search( &self, query: &[f32], limit: usize, galaxy_filter: Option<Galaxy>, ) -> Vec<VectorSearchResult>

Search for the most similar vectors to a query embedding.

Returns results sorted by cosine similarity (highest first). Optionally filter by galaxy.

pub fn search_similar_to( &self, memory_id: Uuid, limit: usize, ) -> Vec<VectorSearchResult>

Search for similar vectors to a memory’s own embedding.

Excludes the memory itself from results.

pub fn clear(&mut self)

Clear the index.
