Struct RecordingProvider 

pub struct RecordingProvider<M> { /* private fields */ }

包裹任意 BaseChatModel:成功响应后把请求/响应对追加到 JSONL。

Implementations

impl<M> RecordingProvider<M>

where M: BaseChatModel + Send + Sync + 'static, M::Error: Into<ProviderError>,

pub fn new(inner: M, path: impl AsRef<Path>) -> Result<Self>

用内层模型 + 录制文件构造。文件打不开 → Err。

pub fn inner(&self) -> &M

访问内层模型。

pub fn bind_tools(&self, tools: Vec<ToolDefinition>) -> Self

where M: Clone,

绑定工具:返回一个记录该工具集的新实例。

后续 chat 会把工具定义录进 RecordedExchange.tools,让回放侧 能按工具名路由(见 crate::ReplayStrategy::ByToolName)。
