Trait Implementations

impl VecStore for InMemoryVecStore

fn add<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, items: &'life1 [VecStoreItem], collection: Option<&'life2 str>, ) -> Pin<Box<dyn Future<Output = Result<(), VecStoreError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Add items (id, vector, payload).

fn search<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, query_vector: &'life1 [f32], top_k: usize, filter: Option<&'life2 HashMap<String, Value>>, collection: Option<&'life3 str>, ) -> Pin<Box<dyn Future<Output = Result<Vec<VecSearchHit>, VecStoreError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Search by vector.

fn get_by_ids<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, ids: &'life1 [String], collection: Option<&'life2 str>, ) -> Pin<Box<dyn Future<Output = Result<Vec<VecStoreItem>, VecStoreError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Get by ids.

fn delete<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, ids: &'life1 [String], collection: Option<&'life2 str>, ) -> Pin<Box<dyn Future<Output = Result<(), VecStoreError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Delete by ids.

fn upsert<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, items: &'life1 [VecStoreItem], collection: Option<&'life2 str>, ) -> Pin<Box<dyn Future<Output = Result<(), VecStoreError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Upsert items: insert or replace by id. Ensures full payload and avoids delete+add window.
