address a bunch of pedantic clippy lints

these might not all be of interest, so i've split them into separate commits for ease of review

I looked over your changes roughly and it looks great to me! I had been working on something similar, as well, but I did not have the time to upload it. I planned to add more restrictive Clippy lints, see #92, and the changes you submitted are a very good step towards that.

There is only one thing I would like to ask you to change: would you please change the lint level from "warn" to "deny"? In #92, the discussion was mostly about the "deny" level, so I think this would be a good enhancement.

Thanks for the PR @danieleades!

Great to see that @kevinmatthes gives his go. #92 can then nicely expand on this work. I merged #107 already, if you could solve the conflicts this one will follow 👍.
