ares-server 0.7.5

//! ChromaDB vector database integration.
//!
//! This module provides integration with ChromaDB, an open-source embedding database.
//!
//! # Status
//!
//! **Not yet implemented.** This is a placeholder for future development.
//!
//! # Feature Flag
//!
//! Enable with `--features chromadb`
//!
//! # Future Implementation
//!
//! When implemented, this will support:
//! - Creating and managing collections
//! - Adding documents with automatic embedding
//! - Similarity search with metadata filtering
//! - Integration with ChromaDB's Python server
//!
//! # Example (future API)
//!
//! ```rust,ignore
//! use ares::db::ChromaDBStore;
//!
//! let store = ChromaDBStore::new("http://localhost:8000").await?;
//! store.create_collection("documents").await?;
//! store.add("documents", &texts, &metadatas).await?;
//! let results = store.query("documents", "search query", 10).await?;
//! ```
