I've been "funemployed" for a few months and with all that free time and idle hands I wrote a full web framework (think Rails, not Flask) for Rust.
It's boring old MVC, has its own ORM, templates, background jobs, auth, websockets, migrations and more. If you're keen but don't feel like rewriting your app in a different language, Rwf has a WSGI server to run Django (or Flask) inside Rust [1], letting you migrate to Rust at your own pace without disrupting your website.
I think Rust makes a great prototyping and deploy straight to production language. Now it has yet another framework for y'all to play with.
Cheers!
Writing a stable WSGI server is possible, and not very hard with a bit of attention to detail, e.g. thread counts, vacuum (just like good old php-fpm, restart every n requests...), etc. Basically if you implement most options uwsgi has, you're on the right path. It's on the roadmap to make Rwf comparable to running Gunicorn.
