Managing Projects with Cargo

Now that we are familiar with the language and how to write basic programs, we'll level up towards writing practical projects in Rust. For trivial programs that can be contained in a single file, compiling and building them manually is no big deal. In the real world, however, programs are split into multiple files for managing complexity and also have dependencies on other libraries. Compiling all of the source files manually and linking them together becomes a complicated process. For large-scale projects, the manual way is not a scalable solution as there could be hundreds of files and their dependencies. Fortunately, there are tools that automate building of large-scale software projects—package managers. This chapter explores how Rust manages large projects with its dedicated package manager and what features it provides to the developer...

Description

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.

Who is this book for?

The book is aimed at beginner and intermediate programmers who already have familiarity with any imperative language and have only heard of Rust as a new language. If you are a developer who wants to write robust, efficient and maintainable software systems and want to become proficient with Rust, this book is for you. It starts by giving a whirlwind tour of the important concepts of Rust and covers advanced features of the language in subsequent chapters using code examples that readers will find useful to advance their knowledge.

What you will learn

Write generic and type-safe code by using Rust's powerful type system

How memory safety works without garbage collection

Know the different strategies in error handling and when to use them

Learn how to use concurrency primitives such as threads and channels

Use advanced macros to reduce boilerplate code

Create efficient web applications with the Actix-web framework

Use Diesel for type-safe database interactions in your web application

This book is a deep dive into the important topics of Rust, more helpful than the official documentation; however, there was no apparent QA on the code samples. Some of their code is said to work, but doesn't and has errata. For example, in the talk of ownership/borrowing (a very important topic), they screw up on a fundamental point. They define a tuple struct and then create it as if it is a unit struct.struct Foo(u32);...let foo = Foo;Anyone reading the errors from the compiler will be able to fix the error by this point, but they say that it should work as is which led to confusion and slowed my progression through the book.I give this 3 stars because of errors. Good information on the important topics of Rust makes it a useful book for any inspiring Rustacean; bad code examples make it difficult to read and follow.

I love that this book starts with an overview of rust features and concepts, and then continues on with practical examples such as using different types of databases and other "must have" tasks.I started working through code examples in the book and found some that are misleading or won't even compile. Why would anyone still do this? For example, the very first example of a closure "big_closure" refers to a variable z that does not exist anywhere in the program.A quick mention in the introduction that its good to learn to fix compiler errors does not excuse this. A book for beginners should not be rife with invalid examples using the readers lack of industry an excuse. Give me good examples and leave notes for challenges and exercises instead.

I was hoping to use this book as a supplement to the 'real' Rust book ("The Rust Programming Language", Klabnik & Nichols) to get a different perspective on the Rust language. (As many have noted, learning Rust is not a trivial exercise.) After slogging through the first chapter, I have (at least for now) given up on it as a waste of my limited time. The code examples are at best mediocre; they often fail fail to clearly demonstrate the point. Commonly an example will mix 'real' code with 'fake' setup code (as in a very 'you would not really want to do this' way). It is not clear which is which, and the accompanying text often does not make any attempt to clarify. Instead it is up to the reader to figure our what is code worth emulating and what is not. The lack of technical precision (really, a technical book that is weak on the technical?!) is made all the worse by the poor use of language. The book desperately needs an editor. (And a spell checker! I found 'seperate' in Chapter 1! How hard is it to run a spell checker over a text?!) In one paragraph, the main topic item was presented in the singular and then referred to as 'they' after introducing another topic (using a plural). Matching up which pronouns with their antecedents turned into a challenging game - but I did not buy the book for its word puzzles. The result was the mixups, grammatical, and spelling errors served as constant annoyances and too often obscured the technical content, requiring two or three readings of a paragraph to sort things out. Avoid this book. Strongly recommend you start with "The Rust Programming Language" (2018 Edition) Klabnik & Nichols. That plus online resources like Stack Overflow will be all you will need for a quite a while as you learn Rust.

I found the quality of this book to be downright terrible. There are grammar mistakes on almost every page. Text descriptions of the code don't actually match the code listed. There are pages where it is supposed to describe advanced information. The "section" is a single sentence. It looks like the entire section is missing. Considering this is the _Second Edition_ I would have expected grammar and the text to be pretty solid. I was wrong.I was so disappointed I requested a refund. Personally, I think this book should be removed from the store. It's obviously a mistake.
