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.

This chapter will cover various approaches to debugging Rust programs. Rust programs, at the binary level, are very similar to C programs. This means that we can leverage the strong legacy of industry standard debuggers such as gdb and lldb that are used for debugging C/C++ programs and use the same tools to debug Rust code as well. In this chapter, we'll interactively walk through some basic debugging workflow and commands with gdb. We'll also cover integrating the gdb debugger with Visual Studio Code (vscode) editor and, later, give a quick overview of another debugger, called rr.

In this chapter, we will cover the following topics:

  • Introduction to debugging
  • The gdb basics and debugging a Rust program
  • The gdb integration with Visual Studio Code
  • RR debugger—a quick overview
