This chapter introduced you to comfortable frameworks that greatly simplify the writing of microservices: Rouille, Nickel, and Rocket.
The Rouille framework is built around the router! macro and helps you to declare all the paths and methods you need in a simple way. The routing declaration looks similar to how we did it with Hyper, but much, much simpler.
