Struct MemoryVectorStore 

pub struct MemoryVectorStore { /* private fields */ }

A simple in-memory VectorStore.

Thread-safe via Arc<Mutex<_>> — suitable for concurrent Axum handlers. For production use, replace with a dedicated vector database.

Implementations

impl MemoryVectorStore

pub fn new() -> MemoryVectorStore

Create an empty store.

pub fn len(&self) -> usize

Return the number of stored documents.

pub fn is_empty(&self) -> bool

Return true if the store contains no documents.

Trait Implementations

impl Clone for MemoryVectorStore

fn clone(&self) -> MemoryVectorStore

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MemoryVectorStore

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for MemoryVectorStore

fn default() -> MemoryVectorStore

Returns the “default value” for a type.

impl VectorStore for MemoryVectorStore

fn add_documents<'life0, 'async_trait>( &'life0 self, docs: Vec<Document>, ) -> Pin<Box<dyn Future<Output = Result<(), Box<dyn Error + Sync + Send>>> + Send + 'async_trait>>

where 'life0: 'async_trait, MemoryVectorStore: 'async_trait,

Persist a batch of documents (with their embeddings) to the store.

fn search<'life0, 'async_trait>( &'life0 self, query_vector: Vec<f32>, limit: usize, ) -> Pin<Box<dyn Future<Output = Result<Vec<Document>, Box<dyn Error + Sync + Send>>> + Send + 'async_trait>>

where 'life0: 'async_trait, MemoryVectorStore: 'async_trait,

Return the limit documents whose embeddings are most similar to query_vector (cosine similarity, descending).
