Creative Projects for Rust Programmers

By: Carlo Milanesi

Overview of this book

Rust is a community-built language that solves pain points present in many other languages, thus improving performance and safety. In this book, you will explore the latest features of Rust by building robust applications across different domains and platforms. The book gets you up and running with high-quality open source libraries and frameworks available in the Rust ecosystem that can help you to develop efficient applications with Rust. You'll learn how to build projects in domains such as data access, RESTful web services, web applications, 2D games for web and desktop, interpreters and compilers, emulators, and Linux Kernel modules. For each of these application types, you'll use frameworks such as Actix, Tera, Yew, Quicksilver, ggez, and nom. This book will not only help you to build on your knowledge of Rust but also help you to choose an appropriate framework for building your project. By the end of this Rust book, you will have learned how to build fast and safe applications with Rust and have the real-world experience you need to advance in your career.

Returning JSON data

The previous section returned data in plain text. This is unusual in a web service and rarely satisfactory. Usually, web services return data in JSON, XML, or another structured format. The json_db project is identical to the memory_db project, except for its returning data in the JSON format.

First of all, let's see what happens when the same curl commands from the previous section are executed on it, as follows:

  • The insertions have the same behavior because they just printed a number.
  • The first query should print the following: [1,2,3]. The three numbers are in an array, and so they are enclosed in brackets.
  • The second query should print the following: "Mary Jane". The name is a string, and so it is enclosed in quotation marks.
  • The third query should print the following: [[2,"Jonathan"],[3,"Mary Jane"]]. The sequence of persons is an array of two records, and each of them is an array of two values, which are a number and a string...
