Mastering Rust - Second Edition

By: Rahul Sharma, Vesa Kaihlavirta

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.

Memory Management and Safety

Memory management is a fundamental concept to understand for anyone working with a low-level programming language. Low-level languages don't come with automatic memory reclamation solutions like a built-in garbage collector, and it's the responsibility of the programmer to manage memory that's used by the program. Having knowledge of where and how memory gets used in a program enables programmers to build efficient and safe software systems. A lot of bugs in low-level software are due to improper handling of memory. At times, it's the programmer's mistake. The other times, it's the side effect of the programming language used, such as C and C++, which are infamous for a lot of memory vulnerability reports in software. Rust offers a better, compile-time solution to memory management. It makes it hard to write software that...
