Struct MemoryEmbeddingStore 

pub struct MemoryEmbeddingStore { /* private fields */ }

In-memory embedding store for testing, development, and prototyping.

Uses brute-force O(n) cosine similarity scan for nearest-neighbor search. Data is lost when the process exits. Implements EmbeddingStore.

Implementations

impl MemoryEmbeddingStore

pub fn new() -> Self

Creates an empty in-memory embedding store.

Trait Implementations

impl Default for MemoryEmbeddingStore

fn default() -> MemoryEmbeddingStore

Returns the “default value” for a type.

impl EmbeddingStore for MemoryEmbeddingStore

fn upsert<'life0, 'async_trait>( &'life0 self, record: EmbeddingRecord, ) -> Pin<Box<dyn Future<Output = StoreResult<EmbeddingRecord>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Inserts or updates an embedding record.

fn search<'life0, 'life1, 'async_trait>( &'life0 self, query: &'life1 [f32], limit: usize, ) -> Pin<Box<dyn Future<Output = StoreResult<Vec<ScoredEmbedding>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Returns the limit nearest neighbors to the query vector.
