Learning Rust

By: Vesa Kaihlavirta

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.

Structs 101


For this chapter, I am going to ask you to imagine the following scenario. I have a house. My house has a certain number of rooms and each room has a name. Each room has one or more doors and windows and a carpet (with a color), and the rooms have a width and length. We will use structs and enums to model all this.

Structs in Rust are very common; they are used in many facets of the language and are useful to understand and use. In terms of the house example, we'll see how useful they can be.

Variables, variables everywhere

Let's look at the house and create some variables to describe it, as well as types. Start with the house, which can be considered the most basic of objects. We will need only to model the number of rooms it has:

number_of_rooms: i32 

Let's consider rooms next.

Each room will have a number of properties. Is it upstairs or downstairs, assuming it's a two-level house? Number of doors. Number of windows. Types of windows. Do the window have curtains? Wood or carpet...
