Welcome to Comprehensive Rust 🦀

This is a four day Rust course developed by the Android team. The course covers the full spectrum of Rust, from basic syntax to advanced topics like generics and error handling. It also includes Android-specific content on the last day.

The goal of the course is to teach you Rust. We assume you don’t know anything about Rust and hope to:

• Give you a comprehensive understanding of the Rust syntax and language.
• Enable you to modify existing programs and write new programs in Rust.
• Show you common Rust idioms.

On Day 4, we will cover Android-specific things such as:

• Building Android components in Rust.
• AIDL servers and clients.
• Interoperability with C, C++, and Java.

It is important to note that this course does not cover Android application development in Rust, and that the Android-specific parts are specifically about writing code for Android itself, the operating system.

Non-Goals

Rust is a large language and we won’t be able to cover all of it in a few days. Some non-goals of this course are:

• Learn how to use async Rust — we’ll only mention async Rust when covering traditional concurrency primitives. Please see Asynchronous Programming in Rust instead for details on this topic.
• Learn how to develop macros, please see Chapter 19.5 in the Rust Book and Rust by Example instead.

Assumptions

The course assumes that you already know how to program. Rust is a statically typed language and we will sometimes make comparisons with C and C++ to better explain or contrast the Rust approach.

If you know how to program in a dynamically typed language such as Python or JavaScript, then you will be able to follow along just fine too.

This is an example of a speaker note. We will use these to add additional information to the slides. This could be key points which the instructor should cover as well as answers to typical questions which come up in class.
