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 10. Creating Your Own Crate

Most languages allow for external libraries to be created. These typically contain commonly used pieces of code that are for general use. For example, libraries for deserializing JSON are fairly common, as are math libraries. Rust is no exception. It allows for the creation of libraries (known as crates). These crates can be kept to yourself or distributed however you see fit. The metadata about crates is stored on a public service, at https://crates.io/.

In this chapter, we will cover the following topics:

  • How crates are created
  • How the directory structure is used
  • How crates are made up of modules
  • How to include your crate within your code
  • How scopes are used with your modules
