I will no longer be able to assist with development nor debugging actual issues with the software... Quite juvenile behavior from the devs. It stemmed from this issue where the devs continuously argued in public by opening and closing an issue. Anyway, thought I would keep y'all apprised of the situation, since these are the people maintaining the software you are currently using.
Sure you can doubt me as much as you want (and this is probably a healthy attitude). I tend to educate myself, and learn from experience (and that I dare to say, I do have...). As you may have guessed, I really recommend looking into it, there's so many good design decisions with Rust (and the ecosystem). As a starting point/library: axum would be the web-framework I'd recommend to use (as it uses Rust quite idiomatically). And for e.g. service communication via grpc, tonic is quite nice. As database abstraction layer the last time I have used sqlx which was quite convenient to use. (So far with a "classic" web-stack). And rust-analyzer is probably the best language server I have used (and felt the fast development over the time (with "successful" switch of the maintainer), which speaks for itself as well...).
Btw. it also really depends on what you actually mean with "web backend development". I.e. "just" writing a web-server that takes connections via HTTP or something deeper the stack...
I like your attitude and approach to this conversation. Thanks for not escalating into a useless argument and making the discussion educational.
