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

Extending Cargo and tools


Cargo can also be extended to incorporate external tools for enhancing the development experience. It is designed to be as extensible as possible. Developers can create command-line tools and Cargo can invoke them via simple cargo binary-name syntax. In this section, we'll take a look at some of these tools.

Subcommands and Cargo installation

Custom commands for Cargo fall under the subcommand category. These tools are usually binaries from crates.io, GitHub, or a local project directory, and can be installed by using cargo install <binary crate name> or just cargo install when within a local Cargo project. One such example is the cargo-watch tool.

cargo-watch

Cargo-watch helps you shorten your fix, compile, run cycle by automatically building your project in the background whenever you make changes to your code. By default, this just runs Rust's type checker (the cargo check command) and does not undergo the code generation phase (which takes time) and shortens...
