Struct VectorBackendStore 

pub struct VectorBackendStore { /* private fields */ }

Adapter over the kernel’s VectorBackend (HNSW, DiskANN, hybrid). The backend’s dimensionality must be DIMS. The backend id is a 64-bit hash of (instance, id); a hash collision between two different pairs is refused rather than overwriting.

Implementations

impl VectorBackendStore

pub fn new(backend: Arc<dyn VectorBackend>) -> Self

Wrap backend.

pub fn persistent( backend: Arc<dyn VectorBackend>, path: &Path, max_log_bytes: u64, ) -> Result<Self, OpenError>

Wrap backend and keep every accepted batch in the log at path (capped at max_log_bytes). Records already in the log are replayed into backend first, so a restarted owner has what it had.
