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.

Program execution models

"An evolving system increases its complexity unless work is done to reduce it."

- Meir Lehman

In the early 1960s, before multitasking was even a thing, programs written for computers were limited to a sequential execution model, where they were able to run instructions one after the other in chronological order. This was mainly due to limitations in how many instructions the hardware could process during that time. As we shifted from vacuum tubes to transistors, then to integrated chips, the modern day computer opened up possibilities to support multiple points of execution in programs. Gone are the days of sequential programming model where computers had to wait for an instruction to finish before executing the next one. Today...
