Expand description

A trait that houses methods related to handlers that can be wrapped with middleware.

Provided Methods§

Source

fn wrap_with<M: Fn(Handler<E>) -> Handler<E>>(self, middleware: M) -> Handler<E>
where Self: 'static + Fn(Request, Context) -> Result<Response<Body>, E> + Sized,

Wraps a Handler with the provided middleware, returning a new Handler.

Source

fn handler(self) -> Handler<HandlerError>
where Self: 'static + Fn(Request, Context) -> Result<Response<Body>, E> + Sized, E: Send + Sync + Fail + From<Error>,

Returns a Handler that maps errors to HandlerError, suitable for passing directly to the lambda macro.
