httpward_core::httpward_middleware::pipe

Struct HttpWardMiddlewarePipe

pub struct HttpWardMiddlewarePipe { /* private fields */ }

Expand description

Public wrapper around shared pipeline storage. The internal Vec is wrapped in an Arc so cloning the pipe is cheap (one atomic increment).

Implementations§

Source §

impl HttpWardMiddlewarePipe

Source

pub fn new() -> Self

Create an empty, cheap-to-clone pipe.

Source

pub fn len(&self) -> usize

Number of middlewares in the pipe.

Source

pub fn is_empty(&self) -> bool

Source

pub fn add_layer<M>(&self, mw: M) -> Self
where M: HttpWardMiddleware + Send + Sync + 'static,

Add a middleware to the pipe (returns a new pipe for builder pattern compatibility)

Source

pub fn add_boxed_layer(&self, mw: Arc<dyn HttpWardMiddleware>) -> Self

Add a boxed middleware (Arc) into the pipe. This is useful when the middleware is created dynamically (plugins).

Source

pub fn get_layer_by_name( &self, name: &str, ) -> Option<&Arc<dyn HttpWardMiddleware>>

Find layer by name (middleware may return a name via name()). Returns a reference to the boxed middleware if found.

Source

pub async fn execute_middleware<S>( &self, inner: S, ctx: Context<()>, req: Request<Body>, ) -> Result<Response<Body>, BoxError>
where S: Service<(), Request<Body>, Response = Response<Body>> + Clone + Send + Sync + 'static, S::Error: Error + Send + Sync + 'static,

Execute the middleware chain for a concrete inner service S.

This converts the concrete inner service to a boxed type (BoxService) once, borrows a slice from the internal Arc<Vec<…>> and runs the optimized Next. Hot path: no atomic ops per middleware.
