Mastering Rust. - Second Edition

By: Rahul Sharma

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.

RR debugger – a quick overview

Apart from gdb and lldb, rr is another powerful debugger that is quite helpful in debugging multi-threaded code which is harder to debug due to its non-determinism. Often, when debugging multi-threaded code, a certain section of code triggers a bug but fails to reproduce in subsequent executions of the program.

Bugs arising due to multi-threaded code are also referred to as heisenbugs.

The rr debugger can perform a reproducible debugging session for non-deterministic, multi-threaded code. It does this by recording the debugging session, which you can replay and track incrementally to close in on the issue. It does this by first saving the trace of the program to disk with all the required information to reproduce the program execution.

One of the limitations of rr is that it is only supported on Linux and on Intel CPUs as of now. To set up...
