Right. I've been following Rocket for a few years when it was most active but the maintainer has for past couple years been focused elsewhere (I take no issue with that, open source is largely volunteer work after all). v0.5 RCs support async and works well from my experience, ymmv. Axum is great. Actix-web is good too.
Have you looked at Bevy before? There is a popular Rust YouTuber that posts videos of his Bevy projects. Definitely look there for inspiration.
Is anyone here attending? Which talks interested in you the most?
