Struct MiddlewareStack 

pub struct MiddlewareStack<I, O> { /* private fields */ }

Ordered list of middlewares. before_invoke runs first→last; after_invoke runs in reverse (last registered → first registered), matching standard middleware ordering.

Implementations

impl<I, O> MiddlewareStack<I, O>

where I: Send + 'static, O: Send + 'static,

pub fn new() -> Self

Empty stack.

pub fn push(self, m: Arc<dyn Middleware<I, O>>) -> Self

Append a middleware to the end of the chain.

pub fn len(&self) -> usize

Number of registered middlewares.

pub fn is_empty(&self) -> bool

True if no middlewares are registered.

pub fn middlewares(&self) -> &[Arc<dyn Middleware<I, O>>]

Borrow the registered middlewares (read-only).
