Each Handler has its own handle_request and handle_response methods. Handlers are executed by order while handling a request, and by the reverse order while handling the response. The order in which handle_request and handle_response functions are executed is summarized in the next flow diagram:

Every Handler is a struct implementing de RhodHandler trait, while the Service is a struct implementing the RhodService trait.

RhodHandlers + RhodService conforms a RhodStack

To use Rhodium, you just have to create a RhodStack, set the socket address where the hyper server will listen, and the protocol to be used (HTTP).

If the Handler i returns an error while handling a request: catch_request functions are called for the next handlers (Handler i+1, i+2, ..., n), and then the flow is ended.

If the Service returns an error: the flow is ended If the Handler i returns an error while handling a response: catch_response functions are called for the next handlers (Handler i-1, i-2, ..., 1), and then the flow is ended.
