Hands-On Microservices with Rust

By: Denis Kolodin

Overview of this book

Microservice architecture is sweeping the world as the de facto pattern for building web-based applications. Rust is a language particularly well-suited for building microservices. It is a new system programming language that offers a practical and safe alternative to C. This book describes web development using the Rust programming language and will get you up and running with modern web frameworks and crates with examples of RESTful microservices creation. You will deep dive into Reactive programming, and asynchronous programming, and split your web application into a set of concurrent actors. The book provides several HTTP-handling examples with manageable memory allocations. You will walk through stateless high-performance microservices, which are ideally suitable for computation or caching tasks, and look at stateful microservices, which are filled with persistent data and database interactions. As we move along, you will learn how to use Rust macros to describe business or protocol entities of our application and compile them into native structs, which will be performed at full speed with the help of the server's CPU. Finally, you will be taken through examples of how to test and debug microservices and pack them into a tiny monolithic binary or put them into a container and deploy them to modern cloud platforms such as AWS.

Summary

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.

The Nickel framework is also pretty simple to use and is inspired by the Express framework of JavaScript.

The Rocket framework is pretty cool and helps you to write a handler in an intuitive, clear style, but it needs the nightly version of the compiler.

The Gotham framework is an asynchronous framework that's based on the tokio and hyper crates. It allows you to use all of the benefits of asynchronous applications: handling thousands of requests in parallel and utilizing all resources completely. We created...
