It will happen, but it's not something you should do today. The async ecosystem in Rust is not yet ready for prime time, there are key language and stdlib features that are just missing. And this in turn holds the web ecosystem back. If you write a web backend in Rust today, you might just do a lot of pointless work that you'll have to rewrite in the future anyway as more advanced frameworks come along and the earlier ones are practically abandoned.
