Creative Projects for Rust Programmers

By: Carlo Milanesi

Overview of this book

Rust is a community-built language that solves pain points present in many other languages, thus improving performance and safety. In this book, you will explore the latest features of Rust by building robust applications across different domains and platforms. The book gets you up and running with high-quality open source libraries and frameworks available in the Rust ecosystem that can help you to develop efficient applications with Rust. You'll learn how to build projects in domains such as data access, RESTful web services, web applications, 2D games for web and desktop, interpreters and compilers, emulators, and Linux Kernel modules. For each of these application types, you'll use frameworks such as Actix, Tera, Yew, Quicksilver, ggez, and nom. This book will not only help you to build on your knowledge of Rust but also help you to choose an appropriate framework for building your project. By the end of this Rust book, you will have learned how to build fast and safe applications with Rust and have the real-world experience you need to advance in your career.

The calc_compiler project

Having an analyzed program (and its matching symbol table), it is easy also to create a program that translates it into another language. To avoid introducing a new language, the Rust language has been used here as a target language, but translating to other high-level languages would be no more difficult.

To run it, go into the calc_compiler folder and type cargo run data/sum.calc. After compiling the project, the program will print the following:

Compiled data/sum.calc to data/sum.rs

If you go into the data subfolder, you will find the new sum.rs file, containing the following code:

use std::io::Write;

#[allow(dead_code)]
fn input() -> f64 {
let mut text = String::new();
eprint!("? ");
std::io::stderr().flush().unwrap();
std::io::stdin()
.read_line(&mut text)
.expect("Cannot read line.");
text.trim().parse::<f64>().unwrap_or(0.)
}

fn main() {
let mut _a = 0.0;
let mut _b = 0.0;
_a...
