Function langchainMemory

langchainMemory(
    mm: MemoryManager,
    ref: ConversationRef,
): {
    loadContext: (query: string, tokenBudget?: number) => Promise<string>;
    saveTurn: (
        userMessage: string,
        assistantMessage: string,
    ) => Promise<string>;
}
LangChain.js: a chat-history-style memory backed by the governed store. Returns loadContext (retrieve → system string) and saveTurn (persist), which slot into an LCEL chain or a custom BaseChatMemory. Structural typing keeps @langchain/core an optional peer dependency.
Parameters
- mm: MemoryManager
- ref: ConversationRef
Returns {
    loadContext: (query: string, tokenBudget?: number) => Promise<string>;
    saveTurn: (
        userMessage: string,
        assistantMessage: string,
    ) => Promise<string>;
}
