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.

The need for logging frameworks

We now know why logs are important. The next question however is how do we integrate logging capabilities in our application? The simplest and most straightforward way to get your application to log events is to have a bunch of print statements sprinkled in code at the required places. This way, we easily get our event logs to the standard output on our Terminal console, which gets our job done, but there's more to be desired. In quite a few cases, we also want our logs to persist for analysis at a later point in time. So, if we want to collect the output from our print statements to a file, we have to look for additional ways such as piping the output to a file using the shell output redirection facility, which is basically plumbing a different set of tools to get to the goal of getting logs from our application to different outputs. As it...
