Struct PgVectorIndex 

pub struct PgVectorIndex { /* private fields */ }

A no-op VectorIndex for use with PostgreSQL + pgvector.

Because pgvector handles vector storage and similarity search natively inside PostgreSQL, there is no need for a separate in-process HNSW index. All vector operations are performed via SQL in PgStorage.

The only meaningful state tracked here is the element count, maintained with an AtomicUsize so callers can still query len() / is_empty().

Implementations

impl PgVectorIndex

pub fn new() -> Self
