The Complete Rust Programming Reference Guide

Overview of this book

Rust is a powerful language with a rare combination of safety, speed, and zero-cost abstractions. This Learning Path is filled with clear and simple explanations of its features along with real-world examples, demonstrating how you can build robust, scalable, and reliable programs. You’ll get started with an introduction to Rust data structures, algorithms, and essential language constructs. Next, you will understand how to store data using linked lists, arrays, stacks, and queues. You’ll also learn to implement sorting and searching algorithms, such as Brute Force algorithms, Greedy algorithms, Dynamic Programming, and Backtracking. As you progress, you’ll pick up on using Rust for systems programming, network programming, and the web. You’ll then move on to discover a variety of techniques, right from writing memory-safe code, to building idiomatic Rust libraries, and even advanced macros. By the end of this Learning Path, you’ll be able to implement Rust for enterprise projects, writing better tests and documentation, designing for performance, and creating idiomatic Rust code. This Learning Path includes content from the following Packt products: • Mastering Rust - Second Edition by Rahul Sharma and Vesa Kaihlavirta • Hands-On Data Structures and Algorithms with Rust by Claus Matzinger

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 to web frameworks. It is designed to be used as a foundational crate to build higher-level web frameworks. It uses the...
