Rust Programming Cookbook

By: Claus Matzinger

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.

Sending web requests

Over recent years, web requests have become an important part of many applications. Almost anything integrates with some kind of web service, even if it's only diagnostics and usage statistics. HTTP's versatility has proven to be a great asset in a more centralized computing world.

One of the libraries in this recipe (surf) is cutting edge and depends on an unstable (at the time of writing this) async/await feature of Rust. Depending on when you read this, the library or async/await in Rust may have changed—in that case, please open an issue on the accompanying GitHub repository so we can provide a working example for other readers.

Making these web requests has not always been straightforward in any language, especially with regard to sending and receiving data types, variables, and more. Since Rust does not come with web request modules...
