2//! Memory system for conversation history management.
3//!
4//! Provides conversation memory management functionality.
5//!
6//! # Core Concepts
7//!
8//! - **BaseMemory**: Base trait for memory.
9//! - **ConversationBufferMemory**: Simple conversation buffer.
10//! - **ConversationBufferWindowMemory**: Conversation buffer with window.
11//! - **ConversationSummaryMemory**: LLM-based summary compression.
12//! - **ConversationSummaryBufferMemory**: Hybrid compression (summary + recent messages).
13//! - **PersistentMemory**: Trait for persistent memory storage.
14//! - **ContextWindow**: Fits messages within a token budget.
15//!
16//! # Feature Flags
17//!
18//! - `mongodb-persistence` — Enables `MongoPersistentMemory` (MongoDB-backed persistent memory).
19//! - `vectorstore-memory` — Enables `VectorStoreRetrieverMemory` (vector-store-backed memory).
