Struct VectorIndexBuilder 

pub struct VectorIndexBuilder { /* private fields */ }

Builder for VectorIndex.

Implementations

impl VectorIndexBuilder

pub fn metric(self, metric: DistanceMetric) -> Self

Set the distance metric.

pub fn config(self, config: HnswConfig) -> Self

Set the HNSW configuration (only effective for HNSW indexes).

This config is ignored when the builder was started with VectorIndex::ivfflat — the index type is never changed by this method. Use ivfflat_config to configure IVFFlat indexes.

pub fn ivfflat_config(self, config: IvfFlatConfig) -> Self

Set the IVFFlat configuration (only effective for IVFFlat indexes).

pub fn concurrent(self) -> Self

Create the index concurrently (non-blocking).

pub fn if_not_exists(self) -> Self

Add IF NOT EXISTS clause.

pub fn build(self) -> VectorResult<VectorIndex>

Build the index definition.

Errors

Returns an error if the configuration is invalid, including if the index name contains characters outside the identifier set (ASCII alphanumeric, _, and . for schema-qualified names).
