Expand description

A trait defining the capabilities of a vector database backend.

Required Methods§

Source

fn add_passages<'life0, 'async_trait>( &'life0 self, passages: Vec<Passage>, ) -> Pin<Box<dyn Future<Output = Result<Vec<String>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Ingests a list of passages into the store.

Source

fn search<'life0, 'life1, 'async_trait>( &'life0 self, query_embedding: &'life1 [f32], limit: usize, ) -> Pin<Box<dyn Future<Output = Result<Vec<Passage>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Searches for the nearest neighbors given a query embedding.
