paperclip VS rust-fastapi-experiments

The first bit I tried was following pieces of the official actix-web tutorial in order to get a tiny little web server started locally. This went fine, but was actually a big mistake as that tutorial teaches you to use macros to define endpoints which, at the time of writing, Paperclip does not support.

The biggest issue with Paperclip is that it only currently supports OpenAPI v2. There is work in progress to add v3 support, but it's just that: in progress. This means that if I really want to supplant FastAPI with this actix-web w/ Paperclip combo, I'm going to have to write my own v3 implementation. There is a GitHub Issue which talks about the intended strategy for achieving this being somehow based on converting a v2 spec to v3. I'm not sure how possible this will be considering there are some important features missing from v2. It makes more sense to me for this to be a different feature via cargo flag (or at least a different module).

The code works... but barely. If you want to see the end result, I have put it up in a GitHub Repository where I also intend to add future experiments in other frameworks. If you haven't gathered as much from all of the text above, this code is fragile, slow, and in no way recommended for production. But if you're more experienced (or dedicated) than I am and want to try your hand at making it better, go for it!
