Rust Standard Library Cookbook

By: Jan Hohenheim, Daniel Durante

Overview of this book

Mozilla’s Rust is gaining much attention with amazing features and a powerful library. This book will take you through varied recipes to teach you how to leverage the Standard library to implement efficient solutions. The book begins with a brief look at the basic modules of the Standard library and collections. From here, the recipes will cover packages that support file/directory handling and interaction through parsing. You will learn about packages related to advanced data structures, error handling, and networking. You will also learn to work with futures and experimental nightly features. The book also covers the most relevant external crates in Rust. By the end of the book, you will be proficient at using the Rust Standard library.

Working with bit fields

Programs written in C don't have the possibility to use the Builder Pattern (Chapter 1, Learning the Basics; Using the builder pattern) to provide users with combinable options. Instead, they have to rely on bit fields. As C has historically become the lingua franca of system languages, you will have to interact with a lot of C code if you plan on wrapping existing programs in a Rust interface or vice versa. Because of this, you will sooner or later come in contact with bit fields. As Rust's enum is way more complex than a C enum, you have to instead rely on the bitflags crate to provide you with all of the necessary functionality to comfortably handle bit fields.
