Overview of this book

Rust is a powerful language with a rare combination of safety, speed, and zero-cost abstractions. This Learning Path is filled with clear and simple explanations of its features along with real-world examples, demonstrating how you can build robust, scalable, and reliable programs. You’ll get started with an introduction to Rust data structures, algorithms, and essential language constructs. Next, you will understand how to store data using linked lists, arrays, stacks, and queues. You’ll also learn to implement sorting and searching algorithms, such as Brute Force algorithms, Greedy algorithms, Dynamic Programming, and Backtracking. As you progress, you’ll pick up on using Rust for systems programming, network programming, and the web. You’ll then move on to discover a variety of techniques, right from writing memory-safe code, to building idiomatic Rust libraries, and even advanced macros. By the end of this Learning Path, you’ll be able to implement Rust for enterprise projects, writing better tests and documentation, designing for performance, and creating idiomatic Rust code. This Learning Path includes content from the following Packt products: • Mastering Rust - Second Edition by Rahul Sharma and Vesa Kaihlavirta • Hands-On Data Structures and Algorithms with Rust by Claus Matzinger

Cargo and crates


When projects get large, a usual practice is to refactor code into smaller, more manageable units as modules or libraries. You also need tools to render documentation for your project, how it should be built, and what libraries it depends on. Furthermore, to support the language ecosystem where developers can share their libraries with the community, an online registry of some sort is often the norm these days.

Cargo is the tool that empowers you to do all these things, and https://crates.io is the centralized place for hosting libraries. A library written in Rust is called a crate, and crates.io hosts them for developers to use. Usually, a crate can come from three sources: a local directory, an online Git repository like GitHub, or a hosted crate registry like crates.io. Cargo supports crates from all of these sources.

Let's see Cargo in action. If you ran rustup, as described in the previous chapter, you will already have cargo installed, along with rustc. To see what commands...
