Good luck on your project! Be sure to visit r/rust in case you have any trouble. The people over there are very helpful.

There are couple books/guides around about good practices in rust. You should be able to find with proper googling. If you can't, comment here. I should be able to dig it out from my bookmarks.

And about Douane, I don't know a lot about what you said, so I can't comment on it. It definitely didn't feel polished but it was honestly the best one around, so again, good luck with your new endeavor.
