Struct MultimodalRetriever 

pub struct MultimodalRetriever { /* private fields */ }

Retriever over a shared image/text vector space.

Implementations

impl MultimodalRetriever

pub fn new( store: Arc<dyn VectorStore>, vision: Arc<dyn VisionEmbeddings>, ) -> Self

Creates a multimodal retriever over store, embedding both modalities with the shared-space vision model.

pub async fn retrieve_modality( &self, query: &str, k: usize, modality: ModalityFilter, ) -> Result<Vec<Document>, RetrieverError>

Retrieves with a text query restricted to modality.

pub async fn retrieve_with_scores_modality( &self, query: &str, k: usize, modality: ModalityFilter, ) -> Result<Vec<SearchResult>, RetrieverError>

Retrieves with a text query, returning scores and modality metadata.

pub async fn retrieve_by_image( &self, image: &ImageInput, k: usize, modality: ModalityFilter, ) -> Result<Vec<Document>, RetrieverError>

Retrieves with an image query (image→image / image→text search).
