Struct ConversationBufferMemory 

pub struct ConversationBufferMemory { /* private fields */ }

Conversation Buffer Memory

将所有对话历史保存在内存中。

示例

use langchainrust::ConversationBufferMemory;
 
let mut memory = ConversationBufferMemory::new();
 
// 保存对话
let inputs = HashMap::from([("input".to_string(), "你好".to_string())]);
let outputs = HashMap::from([("output".to_string(), "你好！".to_string())]);
memory.save_context(&inputs, &outputs).await?;
 
// 加载记忆
let memory_vars = memory.load_memory_variables(&HashMap::new()).await?;
println!("{:?}", memory_vars.get("history"));
