Async UI itself is quite easy to learn! But there are some prerequisites before you start: you need to know Rust, Async Rust, and the Web API. These are no small things to learn. However, all three are highly applicable. They will be useful even if you don't end up using Async UI.

Rust

If you don't know Rust yet, the Rust Book is a good place to start!

Async Rust

You should know

• what async/await does in Rust
• what the Future trait is
• how to run multiple Futures concurrently (i.e. "joining" Futures)

Mastery of manual Future implementation, Pin, or pin-projection is not required for using Async UI.

If you don't know Async Rust yet, or want to brush up on your knowledge, the Async Book is a great resource. Chapter 1, 3, and 6 of the book cover most of what you need for working with Async UI.

Web API

Async UI exposes most of the Web API. Make sure you know some HTML and JavaScript. To start with Async UI, you only need the basics: how to get the text value in an <input>, how to disable a <button>, etc.

The MDN Web Docs is a good reference for the Web API.
