Cuts down on the has table size and generally doesn't loose any information.

I completely agree that rust is for smart enthusiastic people who like sending their time making really complicated abstractions. That's the problem with rust is that you waste your time building these abstractions. You send your time debugging your programming language knowledge rather then debugging the application.
One reason your program might be slow is because I don't think those functions that take in readers and writers do any buffering so you might get a decent speedup by wrapping your files into std::io::BufReader and std::io::BufWriter respectively

I wana make a lang that is like c but safe and functional. Like varibles are functions that return stuff. And if u need weird stuff u have something like a class or something where u can modify the intern varibles of the function
I personally found it to be not THAT bad. It took me a while to become productive in rust since there is such a large shift in how you implement things. Certain approaches used in C is very hard and/or bad in rust. I would consistently spend my time googling on how I can work with certain data structures and then realize there already was a trait that gives me what I want etc. I think the greatest realization was when I finally understood that rust has a different paradigm to C (Rust is declarative compared to the imperative C). Truly understanding how to work with the borrow checker came with experience. My knowledge in C did help however since rust is sensitive about datatype sizes (see sized and unsized traits) and the knowledge from C and assembly carried over into it. Nowadays rust is clearly my favourite programming language, I've largely replaced C and C++ with Rust, Go and Python.

It is possible that he may have changed his IDE color scheme since then, but without any specific information, I cannot say for certain.
