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.

Using generic data types and trait bounds

A generic data type, generic type, or simply, generic, is a way for programming languages to be able to apply the same routine to different data types.

For example, we want to create a multiplication(a, b) -> c {} function for different data types, u8 or f64. If a language does not have a generic, a programmer might have to implement two different functions, for example, multiplication_u8(a: u8, b: u8) -> u8 and multiplication_f64(a: f64, b: f64) -> f64. Creating two different functions might look simple, but as the application grows in complexity, the branching and figuring out which function to use will be more complex. If a language has a generic, then the problem of multiple functions can be solved by using a single function that can accept u8 and f64.

In the Rust language, we can make a function to use generics by declaring the generics inside angle brackets after the function name as follows:

fn multiplication<T&gt...
