Rust Programming Cookbook

By: Claus Matzinger

Overview of this book

Rust 2018, Rust's first major milestone since version 1.0, brings more advancement in the Rust language. The Rust Programming Cookbook is a practical guide to help you overcome challenges when writing Rust code. This Rust book covers recipes for configuring Rust for different environments and architectural designs, and provides solutions to practical problems. It will also take you through Rust's core concepts, enabling you to create efficient, high-performance applications that use features such as zero-cost abstractions and improved memory management. As you progress, you'll delve into more advanced topics, including channels and actors, for building scalable, production-grade applications, and even get to grips with error handling, macros, and modularization to write maintainable code. You will then learn how to overcome common roadblocks when using Rust for systems programming, IoT, web development, and network programming. Finally, you'll discover what Rust 2018 has to offer for embedded programmers. By the end of the book, you'll have learned how to build fast and safe applications and services using Rust.

Handling JSON payloads

After learning how to create APIs, we need to pass data back and forth. While the path provides one method to do that, anything a little more sophisticated (for example, a long list of things) will quickly show the limitations of these methods. This is why other formats are typically used to structure the data—JSON (http://json.org/) is the most popular for web services. In this chapter, we are going to use the previous API and enhance it by handling and returning JSON.

Getting ready

Let's set up a Rust binary project using cargo new json-handling. Since we are going to serve stuff on the local port 8081, make sure that the port is accessible as well. Additionally, a program such as curl...
