Trait Implementations

impl Clone for SQLiteIVFIndex

fn clone(&self) -> SQLiteIVFIndex

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl VectorIndex for SQLiteIVFIndex

fn dimensions(&self) -> u32

fn index_kind(&self) -> &'static str

fn add(&mut self, doc_id: DocId, vector: Vec<f32>) -> StorageBackendResult<()>

fn add_many( &mut self, doc_id: DocId, vectors: Vec<Vec<f32>>, ) -> StorageBackendResult<()>

fn delete(&mut self, doc_id: DocId) -> StorageBackendResult<()>

fn clear(&mut self) -> StorageBackendResult<()>

fn search_knn( &self, query: &[f32], k: usize, ) -> StorageBackendResult<PostingList>

fn search_threshold( &self, query: &[f32], threshold: f32, ) -> StorageBackendResult<PostingList>

fn count(&self) -> StorageBackendResult<usize>

fn initialize(&mut self) -> StorageBackendResult<()>

Build any auxiliary physical metadata required by this index from its current vector contents. Brute-force indexes need no extra work; persistent IVF and HNSW implementations use this during explicit index creation, while restore paths deliberately skip it.

fn snapshot(&self) -> StorageBackendResult<Arc<dyn VectorIndex>>

Read-only handle suitable for an ExecutionContext.

fn writable_snapshot(&self) -> StorageBackendResult<Box<dyn VectorIndex>>

Independent writable copy used by in-memory engine rollback. The default keeps third-party and persistent implementations source compatible; only indexes hosted by a memory engine need to support it.
