Struct IndexManager 

pub struct IndexManager { /* private fields */ }

Manages physical and logical indexes across all vertex datasets.

Implementations

impl IndexManager

pub fn new( base_uri: &str, schema_manager: Arc<SchemaManager>, backend: Arc<dyn StorageBackend>, ) -> IndexManager

Create a new IndexManager bound to base_uri and the given schema and backend.

pub async fn create_inverted_index( &self, config: InvertedIndexConfig, ) -> Result<(), Error>

Build and persist an inverted index for set-membership queries.

pub async fn create_vector_index( &self, config: VectorIndexConfig, ) -> Result<(), Error>

Build and persist a vector (ANN) index on an embedding column.

pub async fn create_scalar_index( &self, config: ScalarIndexConfig, ) -> Result<(), Error>

Build and persist a scalar (BTree) index for exact-match and range queries.

pub async fn create_fts_index( &self, config: FullTextIndexConfig, ) -> Result<(), Error>

Build and persist a full-text search (Lance inverted) index.

pub async fn create_json_fts_index( &self, config: JsonFtsIndexConfig, ) -> Result<(), Error>

Creates a JSON Full-Text Search index on a column.

This creates a Lance inverted index on the specified column, enabling BM25-based full-text search with optional phrase matching.

pub async fn drop_index(&self, name: &str) -> Result<(), Error>

Remove an index both physically from the Lance dataset and from the schema.

pub async fn rebuild_indexes_for_label(&self, label: &str) -> Result<(), Error>

Rebuild all indexes registered for label from scratch.

pub async fn create_composite_index( &self, label: &str, properties: &[String], ) -> Result<(), Error>

Create composite index for unique constraint

pub async fn composite_lookup( &self, label: &str, key_values: &HashMap<String, Value>, ) -> Result<Option<Vid>, Error>

Lookup by composite key

pub async fn update_inverted_index_incremental( &self, config: &InvertedIndexConfig, added: &HashMap<Vid, Vec<String>>, removed: &HashSet<Vid>, ) -> Result<(), Error>

Applies incremental updates to an inverted index.

Instead of rebuilding the entire index, this method updates only the changed entries, making it much faster for small mutations.

Errors

Returns an error if the index doesn’t exist or the update fails.

Trait Implementations

impl Debug for IndexManager

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
