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.

Getting ready

To test this recipe, you will need a way to easily send HTTP requests. An excellent free tool for this is Postman (, which features a nice and self-explanatory UI. If you'd rather not download anything, you can use your terminal for this. If you're on Windows, you can open PowerShell and enter the following to do an HTTP request:

Invoke-WebRequest -UseBasicParsing <Your URL> -Method <Your method in CAPSLOCK> -Body <Your message as a string>

So, if you wanted to POST the message hello there, my echoing friend to http://localhost:3000/echo, as you will be asked to later in the recipe, you'd need to enter the following command:

Invoke-WebRequest -UseBasicParsing http://localhost:3000/echo -Method POST -Body "Hello there, my echoing friend"

On Unix systems, you can use cURL for that ( The analog command is the following:

curl -X <Your method> --data <Your message> ...
