Rust Web Development with Rocket

By: Karuna Murti

Overview of this book

Looking for a fast, powerful, and intuitive framework to build web applications? This Rust book will help you kickstart your web development journey and take your Rust programming skills to the next level as you uncover the power of Rocket - a fast, flexible, and fun framework powered by Rust. Rust Web Development with Rocket wastes no time in getting you up to speed with what Rust is and how to use it. You’ll discover what makes it so productive and reliable, eventually mastering all of the concepts you need to play with the Rocket framework while developing a wide set of web development skills. Throughout this book, you'll be able to walk through a hands-on project, covering everything that goes into making advanced web applications, and get to grips with the ins and outs of Rocket development, including error handling, Rust vectors, and wrappers. You'll also learn how to use synchronous and asynchronous programming to improve application performance and make processing user content easy. By the end of the book, you'll have answers to all your questions about creating a web application using the Rust language and the Rocket web framework.

Working with a database

Currently, in our application, we are storing user data in a static variable. This is very cumbersome, as it is inflexible and we cannot update the data easily. Most modern applications handling data will use some kind of persistent storage, be it filesystem-backed storage, a document-oriented database, or a traditional RDBMS.

Rust has many libraries to connect to various databases or database-like storage. There's the postgres crate, which works as a PostgreSQL client for Rust. There are also other clients such as mongodb and redis. For object-relational mapping (ORM) and Query Builder, there's diesel, which can be used to connect to various database systems. For connection pool management, there are the deadpool and r2d2 crates. All crates have their strengths and limitations, such as not having an asynchronous application.

In this book, we're going to use sqlx to connect to an RDBMS. sqlx claims to be an SQL toolkit for Rust. It has abstractions...
