tail VS dirs-rs

I'm working on a side-quest, and I just started using unit tests (hurray!): https://github.com/LeCyberDucky/tail/blob/main/src/main.rs

Since the program takes over the terminal when running, my trusty old debugging method of adding print statements everywhere doesn't work all too well here. Therefore, I took on the side quest of creating my own version of the UNIX tool "tail" this weekend. I'll write my debugging statements to a file instead and then use this tool to monitor that file. There are ways to achieve this without writing my own tool, but I wasn't completely satisfied with the stuff I tried (I'm on Windows), so I thought it would be fun and hopefully be too big a detour to implement it myself.

I've been using those today in this small project: https://github.com/LeCyberDucky/tail/blob/main/src/main.rs

There are several libraries that handle directory for you in the appropriate OS-specific manner.

One Rust example being https://github.com/dirs-dev/dirs-rs

> The library provides the location of these directories by leveraging the mechanisms defined by

> the XDG base directory and the XDG user directory specifications on Linux and Redox

> the Known Folder API on Windows

> the Standard Directories guidelines on macOS

Yes. We have dirs for that, folks!

I'm using dirs to get the home directory. However, dirs::home_dir() returns an Option, which I can't quite grasp how to extract the string from, and the repo doesn't have examples for it either.
