Thank you for helping to optimize this project. There is still a lot that needs to be fixed, but I don't know where to start, as I am not the best at Rust development. Shortening strings was a good step, and removing unneeded scripts was needed, however I don't know which ones caused the tests to fail. Code optimization is rare these days, and I appreciate when people take the time to do it. This definitely needs further review.
Also, don't be too hard on yourself. I wouldn't consider this to be a bad chore. I am hoping that you implied this to be a good chore, as it is.
