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.

Optimizing production binaries

After we create the application, we want to prepare the application to accept a real connection. In software development, there's a production environment, also called a release environment or deployment environment. The production environment contains the configuration of the system and software to make it available to the intended customer. In Chapter 2, Building Our First Rocket Web Application, we learned that we can tell the Rust compiler to build release binary when compiling the Rust application. We can use cargo build or cargo run with the extra --release flag.

To refresh, Cargo will read the configuration in Cargo.toml in the [profile.release] section. There are some compilation optimizations we can do to improve the resulting image:

  1. The first one is the number of codegen-units of compilation. Rust compilation can take significant time, and to solve this, the compiler may try to split it into parts and compile them in parallel...
