Mastering Rust. - Second Edition

By: Rahul Sharma

Overview of this book

Rust is an empowering language that provides a rare combination of safety, speed, and zero-cost abstractions. Mastering Rust – Second Edition is filled with clear and simple explanations of the language features along with real-world examples, showing you how you can build robust, scalable, and reliable programs. This second edition of the book improves upon the previous one and touches on all aspects that make Rust a great language. We have included the features from latest Rust 2018 edition such as the new module system, the smarter compiler, helpful error messages, and the stable procedural macros. You’ll learn how Rust can be used for systems programming, network programming, and even on the web. You’ll also learn techniques such as writing memory-safe code, building idiomatic Rust libraries, writing efficient asynchronous networking code, and advanced macros. The book contains a mix of theory and hands-on tasks so you acquire the skills as well as the knowledge, and it also provides exercises to hammer the concepts in. After reading this book, you will be able to implement Rust for your enterprise projects, write better tests and documentation, design for performance, and write idiomatic Rust code.

thread-safety in Rust

In the previous section, we saw how the compiler stops us from sharing the data. If a child thread accesses data mutably, it is moved because Rust won't allow it to be used in the parent thread as the child thread might deallocate it, leading to a dangling pointer dereference in the main thread. Let's explore the idea of thread-safety and how Rust's type systems achieves that.

What is thread-safety?

thread-safety is the property of a type or a piece of code that, when executed or accessed by multiple threads, does not lead to unexpected behavior. It refers to the idea that data is consistent for reads while being safe from corruption when multiple threads write to it.

Rust only protects...
