pub struct MiddlewareStack { /* private fields */ }

Ordered stack of middleware layers implementing the onion model.

Implementations

impl MiddlewareStack

pub fn new() -> Self

pub fn push(&mut self, layer: impl ProxyLayer + 'static)

Push a layer onto the stack. Layers are processed in insertion order for requests and reverse order for responses.

pub async fn process_request( &self, request: ProxyRequest, ) -> ProxyResult<Result<(ProxyRequest, usize), ProxyResponse>>

Process a request through all layers. Returns the (possibly modified) request and the index of the deepest layer reached, or a short-circuit response.

pub async fn process_response( &self, response: ProxyResponse, depth: usize, ) -> ProxyResult<ProxyResponse>

Process a response back through layers in reverse order. depth is the number of layers the request passed through.

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize
