}

An installed graph candidate source for one database backend.

None means this model has no graph this consumer may serve and licenses the existing exact sqlite-vec fallback. Errors propagate rather than silently changing route. Implementations merge the registered consumer’s fresh tail before returning candidates.

Required Methods

fn backend_id(&self) -> &str

Backend identity whose note vectors the graph indexes.

fn serves_backend(&self, runtime: &KhiveRuntime) -> bool

Match the actual opened backend, not only its logical name. Two independently opened databases may both have the default main ID.

fn search<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, token: &'life1 NamespaceToken, model: &'life2 str, query_embedding: &'life3 [f32], top_k: u32, ) -> Pin<Box<dyn Future<Output = RuntimeResult<Option<Vec<VectorSearchHit>>>> + Send + 'async_trait>>

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

Return ANN plus fresh-tail candidates in the same score and ordering contract as VectorStore::search.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
