Maybe it's been fixed , but when I tired Rocket last year I couldn't get it to really work.
I would like Flutter to take over since it combines the best of Java /C# ( types) with the best of JavaScript/ Python ( dynamic variables which can be any type ).
See: https://rocket.rs/ https://actix.rs/
But, of course, the demo code is always easy. The real nightmare starts as soon as your application became complex enough, that the demo no longer fit and you need to manually spawn something (To handle TCP connection before it hits the framework for example) rather than just "actix_web::main" or "tokio::main".
