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...

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.
