//! Index implementations for Stoolap
//!
//! This module provides all index structures used by the storage engine:
//!
//! - [`BTreeIndex`] - B-tree index for range queries and sorted access
//! - [`HashIndex`] - Hash index for O(1) equality lookups
//! - [`BitmapIndex`] - Bitmap index for low-cardinality columns
//! - [`HnswIndex`] - HNSW index for approximate nearest neighbor search
//! - [`MultiColumnIndex`] - Composite index for multi-column queries
//! - [`PkIndex`] - Primary key index (virtual, auto-created)
