聊天模型基础 trait

继承自 BaseLanguageModel，专门用于聊天场景。 接受消息列表作为输入，返回 AI 消息。

Required Methods§

Source

fn chat<'life0, 'async_trait>( &'life0 self, messages: Vec<Message>, config: Option<RunnableConfig>, ) -> Pin<Box<dyn Future<Output = Result<LLMResult, Self::Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

与模型聊天

§参数
  • messages - 消息列表
  • config - 可选配置
§返回

LLM 结果
