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.

Typed HTTP with Hyper

The hyper crate can parse HTTP messages, and has an elegant design with focus on strongly typed APIs. It is designed as a type-safe abstraction for raw HTTP requests, as opposed to a common theme in HTTP libraries: describing everything as strings. For example, HTTP status codes in Hyper are defined as enums, for example, the type StatusCode. The same goes for pretty much everything that can be strongly typed, such as HTTP methods, MIME types, HTTP headers, and so on.

Hyper has both client and server functionality split into separate modules. The client side allows you to build and make HTTP requests with a configurable request body, headers, and other low-level configurations. The server side allows you to open a listening socket and attach request handlers to it. However, it does not include any request route handler implementation – that is left...
