Learning Rust

Overview of this book

Rust is a highly concurrent and high performance language that focuses on safety and speed, memory management, and writing clean code. It also guarantees thread safety, and its aim is to improve the performance of existing applications. Its potential is shown by the fact that it has been backed by Mozilla to solve the critical problem of concurrency. Learning Rust will teach you to build concurrent, fast, and robust applications. From learning the basic syntax to writing complex functions, this book will is your one stop guide to get up to speed with the fundamentals of Rust programming. We will cover the essentials of the language, including variables, procedures, output, compiling, installing, and memory handling. You will learn how to write object-oriented code, work with generics, conduct pattern matching, and build macros. You will get to know how to communicate with users and other services, as well as getting to grips with generics, scoping, and more advanced conditions. You will also discover how to extend the compilation unit in Rust. By the end of this book, you will be able to create a complex application in Rust to move forward with.

Chapter 11. Concurrency in Rust

Computers have come a long way in the last 35 years or so. Originally, we had the likes of the 6502, 6809, and Z80 processors. These were known as single processing units; they could only run a single program at a time and software ran in a linear fashion (this meant that performing two tasks at once wasn't possible).

Processors moved on, and from the single processing units (single-core), we moved on to processors that contained multiple processing units (multi-core). Programming languages evolved to allow for this form of processor, and running multiple operations (threads) at the same time became a reality.

Rust, being a very modern language, also has this ability to multiprocess. All of the benefits are available that you would expect from Rust (such as memory safety and avoiding race conditions), but there are some other things that you need to be aware of.

In this chapter, we will:

  • Understand the mechanisms by which Rust performs concurrent processes
  • Learn...
