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.

Setting a WebAssembly build target

The Rust compiler can be set to compile to a different architecture. The architectures are also called targets. Targets can be identified by using target triple, a string that consists of three identifiers to be sent to the compiler. Examples of targets are x86_64-unknown-linux_gnu and x86_64-apple-darwin.

Targets can be categorized into three tiers, tier 1, tier 2, and tier 3:

  • Tier 1 means that the target is guaranteed to work properly.
  • Tier 2 means that the target is guaranteed to build but, sometimes, the automated test to build the binary for the targets may not pass. The host tools and full standard library for this tier are also supported.
  • Tier 3 means that the Rust code base supports some features of the targets. The build for those targets may or may not exist, and the tooling might not be complete.

Remember that WebAssembly is a binary format for a virtual machine. The Rust compiler has targets for the virtual...
