Rust port of http-cache-semantics

As part of our current push on the dstopic side of things, @yoshuawuyts and I are working on a caching http client that can cache its downloaded data down to cacache.

But there's a piece missing! make-fetch-happen was fortunate enough to be able to use an excellent package called http-cache-semantics which is a fairly complete implementation of http caching logic.

Your mission, should you choose to accept it, is to port http-cache-semantics over to Rust!

Now, I've already spoken with @kornelski about it, and they are sadly unable to pick up another project right now, but they were willing to share that they had already started working on a port, so this would be a great place to start, I think, for anyone willing to pick this up?

Are you interested in doing this? Can you do it in the fairly near future (since this is currently a blocker)? Reply below and let me know! We'd love your help! I'm totally willing to collaborate on this, as well. This is a fantastic way to learn Rust, if you're coming from the JS ecosystem, too.
