I am no hard core web developer, I am new to Rust, I wanted to put up a web server for a simple, low load site, mostly static pages and a simple REST API. Data coming from our CockroachDB database.
As such my comments about Rust web servers is not worth much.
However I'm using Rocket. Selected because I was not aware of any other options but mostly after being fired up by Sergio Benitez presenation on YouTube: "Rocket: Securing the Web at Compile-time": https://www.youtube.com/watch?v=p792bWipnz8. It was also confidence inspiring to hear that people like NPM, System76 and Mozilla are using Rocket in production.
It worked out very well. Simple to use for this Rust newbie. Running reliably for months now.
