How does an async runtime work? And more importantly, why bother with async at all? Is it worth the trouble and added complexity?

Async is arguably one of Rust's most complex and least understood features. As a wise man once said: "Async Rust is Rust on hard mode".

Eylon Levi will be our guide through this maze. In the process of writing a small async runtime, he'll help you explore and learn the inner workings of the system. This way, you will truly understand how async works, and will be able to use it confidently in your own code when you need to.
