Rust/Loco is unironically the most interesting framework right now. Loco follows up the Rails formula pretty closely, and makes easier to learn Rust by taking care of a load of boilerplate code.
Concur on most interesting! I really hope it works out, but am cautious. It is surprising to me seeing the rust web backend scene; many libraries, server frameworks, and users, but they are all Flask-analogs, without the benefit of the reasonably-robust ecosystem Flask has. My suspicion is that people are using them for micro-services and not websites/webapps, but I haven't been able to get a straight answer on this…
I think rust programers are more likely to want flask/rack than Django/rails.
