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

Setting up a Rust development environment


Rust has decent support for most code editors out there, whether it be vim, Emacs, intellij IDE, Sublime, Atom, or Visual Studio Code. Cargo is also well supported by these editors, and the ecosystem has several tools that enhance the experience, such as the following:

  • rustfmt: It formats code according to conventions that are mentioned in the Rust style guide.
  • clippy: This warns you of common mistakes and potential code smells. Clippy relies on compiler plugins that are marked as unstable, so it is available with nightly Rust only. With rustup, you can switch to nightly easily.
  • racer: It can do lookups into Rust standard libraries and provides code completion and tool tips.

Among the aforementioned editors, the most mature IDE experience is provided by Intellij IDE and Visual Studio Code (vscode). We will cover setting up the development environment for vscode in this chapter as it is more accessible and lightweight. For vscode, the Rust community has...
