Rust Web Programming - Second Edition

By: Maxwell Flitton

Overview of this book

Are safety and high performance a big concern for you while developing web applications? With this practical Rust book, you’ll discover how you can implement Rust on the web to achieve the desired performance and security as you learn techniques and tooling to build fully operational web apps. In this second edition, you’ll get hands-on with implementing emerging Rust web frameworks, including Actix, Rocket, and Hyper. It also features HTTPS configuration on AWS when deploying a web application and introduces you to Terraform for automating the building of web infrastructure on AWS. What’s more, this edition also covers advanced async topics. Built on the Tokio async runtime, this explores TCP and framing, implementing async systems with the actor framework, and queuing tasks on Redis to be consumed by a number of worker nodes. Finally, you’ll go over best practices for packaging Rust servers in distroless Rust Docker images with database drivers, so your servers are a total size of 50Mb each. By the end of this book, you’ll have confidence in your skills to build robust, functional, and scalable web applications from scratch.

Registering our views with Rocket

Before we move on to the src/main.rs file, we must ensure that our view functions are available to the src/main.rs. This means going through all the mod.rs files in each view module and declaring the functions that define these views as public. We can then move on to the src/main.rs file and ensure that the following is imported:

#[macro_use] extern crate rocket;
#[macro_use] extern crate diesel;
use rocket::http::Header;
use rocket::{Request, Response};
use rocket::fairing::{Fairing, Info, Kind};

The macro_use declarations should not be a surprise; however, we import the Rocket structs to define our CORS policy. With these crates imported, we now must ensure that the following modules have been declared:

mod schema;
mod database;
mod json_serialization;
mod models;
mod to_do;
mod config;
mod jwt;
mod views;

These modules should all look familiar to you. We then must import our views with the following code:

use views::auth::{login:...
