Let's write an async runtime

• Async

Have you ever wondered what exactly the async/await syntax in Rust really does behind the scenes, or what this whole async runtime business is all about? Perhaps you came across the `Pin` and `Unpin` types and couldn't quite understand why they're needed? Or maybe you saw a long cryptic error message from the Rust compiler regarding your `Future` not implementing `Send` and it confused the hell out of you? Or maybe you know all of that and you always wanted to look into the nitty-gritty of an async runtime implementation but never got around to it? If your answer to any of these questions is "yes", this talk is for you. In this talk, Zeeshan will (or rather attempt to) explain it all. He'll do that the hard way: by writing a simple async runtime. He has never done this before, so either he'll succeed or fail, but one thing is guaranteed: by the end of the talk, we'll all have a much better grasp of async/await machinery in Rust and how async runtimes work than we did before the talk.
