Storing and Retrieving Data

A typical need of any software application is to input/output data by reading/writing data files or data streams or by querying/manipulating a database. Regarding files and streams, unstructured data, or even binary data, is hard to manipulate, and so they are not recommended.

Also, proprietary data formats are not recommended because of the vendor lock-in risk, and so only standard data formats should be used. Fortunately, there are free Rust libraries that come to the rescue in these situations. There are Rust crates available to manipulate some of the most popular file formats, such as TOML, JSON, and XML.

In terms of databases, there are Rust crates to manipulate data using some of the most popular databases, such as SQLite, PostgreSQL, and Redis.

In this chapter, you will learn about the following:

How to read configuration data from a TOML file
How to read or write a JSON data file
How to read an XML data file
How to query or manipulate data in a SQLite database
How to query or manipulate data in a PostgreSQL database
How to query or manipulate data in a Redis database

Key benefits

Work through projects that will help you build high-performance applications with Rust

Delve into concepts such as error handling, memory management, concurrency, generics, and macros with Rust

Improve business productivity by choosing the right libraries and frameworks for your applications

Description

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.

What you will learn

Access TOML, JSON, and XML files and SQLite, PostgreSQL, and Redis databases

Develop a RESTful web service using JSON payloads

Create a web application using HTML templates and JavaScript and a frontend web application or web game using WebAssembly

Build desktop 2D games

Develop an interpreter and a compiler for a programming language

Create a machine language emulator

Extend the Linux Kernel with loadable modules

This book does a wonderful job at introducing the reader to various crates for building numerous projects across various domains in rust. If you're stuck wondering how to get started with concepts such as creating a REST HTTP web server, building your first 2D game or even a Linux kernel module, then this book will guide you to doing so through commonly used crates in Rust.Each chapter is laid out consistently, with each being responsible for a single project (barring the introduction and the final "Future of rust" chapter) with a technical requirements and a "project overview" to give an aim for what is to be built. The chapter then proceeds to go over the various implementation aspects required in each project and finishes off with a summary and questions section, to help the reader improve upon their own knowledge and understanding of the concepts visited within the chapter.The book is geared towards persons who have a working understanding of Rust, and who are looking to cut their teeth by building projects, and does a brilliant job of helping the reader get started.

Love this book overall.One of the gems is for me chaper 8 "Using a Parser Compinator for Interpreting and Compiling" .. special named here the usage and insights in the NOM library, and the straight !! examples.Helped me to get in the right direction. ThanksI see forward the next expanded !!!!, I hope so ;-), version of this book

The creative projects introduced in the first three or four chapters were not very interesting to me. However, the book took several chapters to warm up and by the end I was very pleased with the pace and flavor of the projectsintroduced.Overall, this book portrays a well balanced slice-of-life of what it means to program in Rust from the year it was written. I will gladly hold on to my copy of the book for reference back to some of the more advanced concepts introduced in the book.

The code in the book is not updated, and a lot of examples don't work. Also, I have to login each day and search for the place where I left yesterday; it's too annoying.
