Mastering Rust - Second Edition

By: Rahul Sharma, Vesa Kaihlavirta

Overview of this book

Rust is an empowering language that provides a rare combination of safety, speed, and zero-cost abstractions. Mastering Rust – Second Edition is filled with clear and simple explanations of the language features along with real-world examples, showing you how you can build robust, scalable, and reliable programs. This second edition of the book improves upon the previous one and touches on all aspects that make Rust a great language. We have included the features from latest Rust 2018 edition such as the new module system, the smarter compiler, helpful error messages, and the stable procedural macros. You’ll learn how Rust can be used for systems programming, network programming, and even on the web. You’ll also learn techniques such as writing memory-safe code, building idiomatic Rust libraries, writing efficient asynchronous networking code, and advanced macros. The book contains a mix of theory and hands-on tasks so you acquire the skills as well as the knowledge, and it also provides exercises to hammer the concepts in. After reading this book, you will be able to implement Rust for your enterprise projects, write better tests and documentation, design for performance, and write idiomatic Rust code.

Our app works great, but there are lots of ways we can improve it. If you are feeling ambitious, you can take a look at the following challenges:

  • Improve error handling in the app and handle cases where the network is slow by adding retry mechanisms.
  • Customize the number of stories that get loaded by placing an input field widget on the header bar, and parse and pass that number to the network thread.
  • Add a button to each story to view comments. When the user clicks on the comments button, the app should open a scrollable widget on the right and populate the comments in that story, one by one.
  • Widgets can be styled using CSS. Try adding colors to the story container, depending on the popularity of posts, using the gtk::StyleProvider APIs.
