Learn Egghead, Rust and Xstream

Rust is a modern language that is close to the metal. It's got the performance of C, but with a more friendly syntax and community.

It's also memory safe, and ensures your applications are bug free by catching errors at compile time instead of runtime.

These features make Rust a great choice for developing code for embedded systems, web servers, and CLI apps. You can even compile Rust into WebAssembly in order to run it in-browser!

But as the saying goes, "before you learn to run, you must learn to walk".

In this course, you will write your first Rust application.

Starting from “Hello World” you’ll quickly move on to learning about Rust’s types, configuration files, and the `cargo` package manager along with classics like functions, loops, and handling user input.

More Rust-specific concepts like macros and pattern matching will also be introduced.

Rust is a systems programming language that runs blazingly fast, prevents segfaults, and guarantees thread safety.

Write Your First Program with the Rust Language

[Rustlings](https://github.com/rust-lang/rustlings) is a set of exercises that serves as a great introduction to the Rust language. It covers many concepts from the [Rust book](https://doc.rust-lang.org/book/) by asking you to work through sets of exercises.

This collection walks you through Rustlings in a way that explains what's going on in each exercise. We cover everything from basic types to generics and threading.

Learning Rust by Working Through the Rustlings Exercises

This collection contains videos that explore the basic types in Rust, including **Fixed size Integer**, **Pointer sized Integer**, **Boolean**, **Strings**, **Characters**, **Arrays**, **Tuples** and more.

If you're just starting out learning Rust and [wrote your first program](https://egghead.io/courses/write-your-first-program-with-the-rust-language), this collection is the right place to get more familiar with the language!

Basic Types in Rust

Many languages work on a compilation story to WebAssembly, but Rust is already ready for primetime. Why?


- Rust is a stable language and great replacement for C and C++. 
- Due to the reference and borrowing concept, Rust doesn’t need a Garbage Collector and can be used for a production-ready WebAssembly project. 
- The Rust/Wasm team has built some sophisticated tooling for straightforward interoperability between Rust and JavaScript.

This course gives you the tools to compile to WebAssembly with Rust. Over 11 lessons, we’ll set up a project and explore various paths of communication and interoperability between Rust and JavaScript.

Using WebAssembly with Rust

This is the video companion to the [egghead.io Instructor Guide](https://howtoegghead.com/instructor/).

Screencasting is hard! There are virtually infinite ways to produce one. For an egghead.io lesson we expect several key aspects to be met. We want to make sure that our lessons have depth and clarity. Clarity is important and starts with the technical aspects of recording your screen and voice. Once we have achieved this objective level of clarity, we dip into the stylistic aspects of recording a lesson. The style is subjective, and the goal of an egghead.io lesson is not to have an army of uniform drone producing flavorless video content for the masses.

Our mission is to make you a badass screencaster. We want to push you to another level. We've found that a small set of standard practices will create an awesome experience for the student, and eliminate frustration as we teach by providing a repeatable pattern for success. It’s not complicated. In fact, it is simple, but it isn’t easy.


This course will show you how to produce an egghead.io lesson. We strive for consistency in style, and these lessons will demonstrate the core elements that create our brand screencasts. Let’s learn how together.

Miscellaneous one-off lessons on debugging, productivity hacks, and JavaScript tricks.

JavaScript® (often shortened to JS) is a lightweight, interpreted, object-oriented language with first-class functions, most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic, and supports object-oriented, imperative, and functional programming styles.

Tips and Tricks

The Chrome Developer Tools (DevTools for short), are a set of web authoring and debugging tools built into Google Chrome.

Your page is showing high CPU usage and spinning up your laptop fan, but nothing is visibly happening. What is it doing, and why is it so slow?

This lesson is a real-world performance diagnosis of this very page, right here on egghead. Two infinite (but hidden) animations were causing CPU usage to spike, and Chrome's Task Manager and Performance tools helped uncover the elements causing the problem. You'll see how to use the profiler to record a snapshot, and learn a trick for discovering animations running in the background.

codesandbox.io provides one of the fastest ways to start a new React project. In this lesson, we will take a first look at codesandbox, its interface, and the default React project it creates.

By re-assigning a couple mouse buttons, you can drastically improve the speed you can edit your lessons in Screenflow. This lesson shows how to customize using the Logitech software, but the concept should work for any mouse customization software as well.

Sometimes you have an idea that you want to quickly record, but the idea of setting up a project just to get it recorded gets in your way. I'm going to walk your through scripting away the main setup pain points so that you can focus on creating content.

When making your font sizes large, your code will often get to long to fit on the screen. This lesson shows you how to use "word wrap" or "prettier print width" to adjust your code to fit within the editor.

Reformat Code to Fit the Screen

In this lesson we’ll create a new Rust project using the `cargo new` command and take a look at some of the generated files.

Create a Rust package with the Cargo package manager

In this lesson we take a look at how `println!()` can be used to output multiple variables using formatter placeholders.

In this lesson we’ll create our first “Hello World” Rust program from scratch and will learn how to compile it using `rustc`.

Compile and run a Rust program from scratch

In this lesson we'll learn how to use the `cargo run` command to compile and run a Rust program.

Compile and run a Rust program using Cargo

In this lesson we'll learn how to initialise variables in Rust and how to make them mutable using the `mut` keyword so they can be changed throughout the program.

Variables and Mutability in Rust

In this lesson we'll create a new function that receives parameters and called inside our program's `main()` function.

Write and call a function in Rust

In this lesson we'll briefly discuss the concept of Ownership and Borrowing in Rust, and how expressions can be passed by value and by reference.

In this lesson we'll learn how to read user input from stdin, using Rust's `std::io` module and its `Stdin` object.
