Struct InterceptorChain 

pub struct InterceptorChain { /* private fields */ }

拦截器链 — 按顺序执行多个拦截器（非泛型，支持异构拦截器混合）

Implementations

impl InterceptorChain

pub fn new() -> Self

pub fn push<I: Interceptor>(&mut self, interceptor: I)

添加拦截器（按值，自动 Arc<dyn Interceptor>）

pub fn push_arc(&mut self, interceptor: Arc<dyn Interceptor>)

添加已 Arc 包装的拦截器

pub fn before_all(&self, ctx: &CallContext) -> RIE<()>

before_all — 顺序执行，任一 Err 即停止

pub fn after_all(&self, ctx: &CallContext, result: &mut CallResult)

after_all — 逆序执行，可传递可变 CallResult 让拦截器加工

Trait Implementations

impl Default for InterceptorChain

fn default() -> Self

Returns the “default value” for a type.
