I'm learning how to use Rocket to create an API server.
I have a working example at rust-rocket-demo/main.rs at master · mvolkmann/rust-rocket-demo · GitHub.
My next step was to modify it to use HTTPS, but I found this at Configuration - Rocket Programming Guide": "Warning: Rocket's built-in TLS is not considered ready for production use. It is intended for development use only ."
I guess this means production uses of Rocket are typically placed behind some other server that provides HTTP like nginx, right?
Is there another popular Rust crate for implementing API servers that supports using HTTPS on its own?
