Small Task 2 - Communications

Description

In the second task we will attempt to model basic one client - multiple servers communications. Our simple, made up protocol defines three types of messages: Handshake, GetCount and Post. In this model, a server is only capable of serving one client. A client can establish connections to multiple servers however. Upon successful reception of a message, the server should respond accordingly with a Response.

Your task is to implement both the client and server side behavior, according to method descriptions and tests provided in main.rs. Messages are sent from the client using the .send() method and consumed by servers using their .receive() method. There is no real networking in this task - send() should call receive() on an appropriate server.

Below you can find the description of our protocol:

  • Handshake - should be sent by the client as the first request to establish a proper connection. The message should contain the ip of the client (in the load field). The server should respond with a HandshakeReceived response if the connection has been established succesfully or an UnexpectedHandshake error if its already connected to a client.

  • GetCount - asks the server for its current number of consumed Post requests. The server should respond with a GetCount response containing a value equal to its post_count at the time of handling the request.

  • Post - sends whatever load to the server to ingest. Consuming this request should increase the number of received Post request on the server by one. If the server has not reached its limit yet, it should respond with PostReceived. Otherwise, it should report the ServerLimitReached error.
