//! Collection management for `VelesDB`.
//!
//! A collection is a container for vectors with associated metadata,
//! providing CRUD operations and various search capabilities.
//!
//! # Features
//!
//! - Vector storage with configurable metrics (`Cosine`, `Euclidean`, `DotProduct`)
//! - Payload storage for metadata
//! - HNSW index for fast approximate nearest neighbor search
//! - BM25 index for full-text search
//! - Hybrid search combining vector and text similarity
//! - Metadata-only collections (no vectors) for reference tables
//! - Graph collections for knowledge graph storage (nodes, edges, traversal)
//! - Async operations via `spawn_blocking` (EPIC-034/US-005)
#![allow(clippy::doc_markdown)] // Collection docs contain many API/algorithm identifiers.
#![allow(deprecated)] // Collection is deprecated but used internally throughout this module tree.
