Implementations

impl MiddlewareChain

pub fn new() -> Self

pub fn push(&mut self, middleware: Arc<dyn Middleware>)

pub fn with(self, middleware: Arc<dyn Middleware>) -> Self

pub fn is_empty(&self) -> bool

pub async fn before_model( &self, ctx: &MiddlewareCtx<'_>, req: &mut LLMRequest, ) -> Result<(), String>

正序执行所有 before_model。出错时用中间件 name() 标注是谁挂的。

pub async fn after_model( &self, ctx: &MiddlewareCtx<'_>, msg: &mut Message, ) -> Result<(), String>

逆序执行所有 after_model。出错时用中间件 name() 标注是谁挂的。

pub async fn before_tool( &self, ctx: &MiddlewareCtx<'_>, call: &ToolCall, ) -> Result<ToolDecision, String>

正序询问 before_tool,第一个返回 ShortCircuit 的中间件胜出。 出错时用中间件 name() 标注是谁挂的。

pub async fn after_tool( &self, ctx: &MiddlewareCtx<'_>, call: &ToolCall, result: &mut ContentBlock, ) -> Result<(), String>

逆序执行所有 after_tool。出错时用中间件 name() 标注是谁挂的。
