Learning Rust

Overview of this book

Rust is a highly concurrent and high performance language that focuses on safety and speed, memory management, and writing clean code. It also guarantees thread safety, and its aim is to improve the performance of existing applications. Its potential is shown by the fact that it has been backed by Mozilla to solve the critical problem of concurrency. Learning Rust will teach you to build concurrent, fast, and robust applications. From learning the basic syntax to writing complex functions, this book will is your one stop guide to get up to speed with the fundamentals of Rust programming. We will cover the essentials of the language, including variables, procedures, output, compiling, installing, and memory handling. You will learn how to write object-oriented code, work with generics, conduct pattern matching, and build macros. You will get to know how to communicate with users and other services, as well as getting to grips with generics, scoping, and more advanced conditions. You will also discover how to extend the compilation unit in Rust. By the end of this book, you will be able to create a complex application in Rust to move forward with.

Project 3 – area and volume


This project should help consolidate both testing and documentation for your applications.

You have a simple web service running on a server somewhere. It exists as a test bed for users to send data and receive it back. The service is expecting three strings to be entered, which are as follows:

  • Username (string, non-null, must be more than 6 characters, no spaces)
  • Password (string, non-null, must be more than 8 characters, no spaces, must have 1 capital, 1 number)
  • Command string

The command string is a comma-separated list containing details of whether it is to be a volume or area calculation, the type of shape, and the parameter list.
