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