Advanced Hands-on Rust

Level up Your Coding Skills

by Herbert Wolverson

Accelerate your Rust development with reusable libraries, and build a game development toolkit that helps you quickly create games using the Bevy Engine. Improve your code with testing, benchmarking, and optimization. Unlock Rust’s trait and generic metaprogramming systems to develop code that adapts to fit your needs. Customize libraries with feature flags, and customize language syntax with macros. Master concurrency with threads and asynchronous programming. Structure your programs with reusable state management, menus, user interface elements, and asset management. Quickly build games with reusable physics and collision detection. Make your games pop with animations, particles, and rendering tricks, including parallax layering.

Accelerate your Rust development with intermediate to advanced concepts. Build reusable libraries; unleash generics, traits, macros, and more as you level up your Rust skills. Apply your skills to build a game development toolkit that helps you quickly build 2D games without reinventing the wheel when you start a new project.

Each chapter in this book includes hands-on, practical development using intermediate through advanced Rust. Make learning fun by building games as you apply language concepts. Develop several games and build the tools you need to unleash your creativity or apply the concepts to your own Rust projects.
