Overview of this book

If you are building concurrent applications, server-side programs, or high-performance applications, you will benefit from this language. This book comes with a lot of application-specific recipes to kick-start your development of real-world high-performance applications with the Rust programming language and integrating Rust units into your existing applications. In this book, you will find some 80 practical recipes written in Rust that will allow you to use the code samples right away in your existing applications. These recipes have been tested with stable rust compiler versions of 1.14.0 and above. This book will help you understand the core concepts of the Rust language, enabling you to develop efficient and high-performance applications by incorporating features such as zero cost abstraction and better memory management. We’ll delve into advanced-level concepts such as error handling, macros, crates, and parallelism in Rust. Toward the end of the book, you will learn how to create HTTP servers and web services, building a strong foundational knowledge in server-side programming and enabling you to deliver solutions to build high-performance and safer production-level web applications and services using Rust.

Working on existing Cargo projects

Cargo is a tool that allows the Rust application to declare their various dependencies to ensure that you will able to recreate the build by following the same dependencies and version.

At a higher level, it offers configuration management to the Rust project and helps in reproducing the development environment. Usually, in other languages, it's a very tedious and time-consuming process to maintain the different dependencies and configure them each and every time we deploy the application in a different environment.

Cargo provides features out of the box which enables developers and project managers to ship/deploy Rust projects/applications very quickly and without much hassle; this is a very big advantage over other languages.

Getting ready

We require the Rust compiler, Cargo, and any text editor for coding.

How to do it...

Clone the project from the project repo in this recipe. Close the rand crate from GitHub where it is hosted. Do this by typing the following...
