Overview of this book

Rust 2018, Rust's first major milestone since version 1.0, brings more advancement in the Rust language. The Rust Programming Cookbook is a practical guide to help you overcome challenges when writing Rust code. This Rust book covers recipes for configuring Rust for different environments and architectural designs, and provides solutions to practical problems. It will also take you through Rust's core concepts, enabling you to create efficient, high-performance applications that use features such as zero-cost abstractions and improved memory management. As you progress, you'll delve into more advanced topics, including channels and actors, for building scalable, production-grade applications, and even get to grips with error handling, macros, and modularization to write maintainable code. You will then learn how to overcome common roadblocks when using Rust for systems programming, IoT, web development, and network programming. Finally, you'll discover what Rust 2018 has to offer for embedded programmers. By the end of the book, you'll have learned how to build fast and safe applications and services using Rust.

Calling into Rust from Node.js using FFI

JavaScript is a language that excels in its flat learning curve and flexibility, which leads to impressive adoption rates in various areas outside of the original browser animation. Node.js (https://nodejs.org/en/) is a runtime based on Google's V8 JavaScript engine, which allows JavaScript code to run directly on the operating system (without the browser), including access to various low-level APIs in order to enable IoT-type applications and web services, or even to create and display virtual/augmented reality environments (https://github.com/microsoft/HoloJS). All of this is possible because the Node runtime provides access to native libraries on the host operating system. Let's see how we create a Rust library to call from JavaScript into this.
