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.

This recipe is written with the assumption that you want to use stdin for live interaction over the cli. If you plan on instead piping some data into it (for example, cat foo.txt | stdin.rs on *nix), you can stop treating the iterator returned by lines() as infinite and retrieve the individual lines, not unlike how you retrieved the individual parameters in the last recipe.

There are various calls to trim() in our recipe [35, 45 and 55]. This method removes leading and trailing whitespace in order to enhance the user-friendliness of our program. We are going to look at it in detail in the Using a string section in Chapter 2, Working with Collections.
