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.

Concurrency models with threads

We mainly use threads to perform a task that can be split into sub-problems, where the threads might need to communicate or share data with each other. Now, using the threading model as the baseline, there are different ways to structure our program and control access to shared data. A concurrency model specifies how multiple threads interact with instructions and data shared between them and how they make progress over time and space (here, memory).

Rust does not prefer any opinionated concurrency model and frees the developer in using their own models depending on the problem they are trying to solve through third party crates. So, other models of concurrency exist that includes the actor model implemented as a library in the actix crate. There are other models too, such as the work stealing concurrency model implemented by the rayon crate. Then...
