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

Useful procedural macro crates


As procedural macros can be distributed as crates, a lot of emerging helpful macro crates are available, which can be found at crates.io. Using them can greatly reduce the boilerplate you need to write for generating Rust code. Some of them are as follows:

  • derive-new: A derive macro provides a default all-fields constructor for structs and is quite customizable.
  • derive-more: A derive macro that circumvents the limitation where we wrap a type for which we already have a lot of traits auto-implemented, but lose the ability to create our own type wrapping for it. This crate helps us provide the same set of traits, even on these wrapper types.
  • lazy_static: This crate provides a function-like procedural macro called lazy_static!, where you can declare static values that require dynamically initialized types. For example, you can declare a configuration object as a HashMap and can access it globally across the code base.
