Handling requests

The Rouille framework contains a router! macro that helps you declare a handler for every path and HTTP method. If we add a handler function that is called from a closure we used in the start_server function call, the router! macro expects a request instance as the first argument and the desired number of request handlers. Let's analyze the four handler functions in order.

The following is a simple handler that expects a GET method and returns a text response:

(GET) (/) => {

Response::text("Users Microservice")

},
