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.

Shared mutable ownership

Sharing ownership is great for read-only data. However, mutability is sometimes required, and Rust provides a great way to achieve this. If you recall the rules of ownership and borrowing, if there is a mutable reference, it has to be the only reference to avoid anomalies.

This is typically where the borrow checker comes in: at compile time, it makes sure that the condition holds true. This is where Rust introduces the pattern of interior mutability. By wrapping the data into a RefCell or Cell-type object, immutable and mutable access can be handed out dynamically. Let's see how this works in practice.
