On my journey of teaching myself Rust through The Rust Programming Language, Rust By Example, and supplemental YouTube videos, I wanted to create a CLI app that uses the fundamentals of any programming language; that is, control flow, file I/O, data structures, etc.
CLI apps are a common type of lab I've done while in my university's earlier courses, so I thought creating one in a language I was unfamiliar with would be good practice to create something I would actually use (as opposed to making 3210948321 temporary new.txts in Notepad++), while simultaneously getting my hands dirty in the language and its features (ie. the borrow checker).
What I thought would be a small one or two day project has taken me longer than I expected. I underestimated how strict Rust's compiler actually is, as well as how verbose the syntax is (although this is for good reason as laid out in The Book).
I actually redid the entirety of the project from scratch because of how convoluted my first implementation was.
I will say though, developing this mini-project has made me think about a lot of things that I had never considered while programming in Python or C++ (such as design choices revolving around typing, scopes, etc.). My main takeaway so far is that borrowing and ownership are concepts that are really important in Rust.
With that being said, all functionality it complete as of 2025/12/18, with minor refactoring and one bug-fix being necessary.
