I’m working on a music collection manager with a TUI for myself. I prefer to buy and own music instead of just streaming and I have a selhosted server with ZFS and backups where I keep the music and from which I can stream or download to my devices. There are websites which help you keep track of what you own and have wishlists, but they don’t really satisfy my needs so I decided to create my own. Its main feature is to have an easier overview of what albums I own and don’t own for the artists I’m interested in and to maintain a wishlist based on this for my next purchases. I’m doing it in Rust, because it’s a hobby project and I want to get better at Rust. However, it has paid off in other ways. The type system has allowed me to create a UI that is very safe to add features to without worrying about crashes. Sometimes I actually have to think why it didn’t crash only to find that Rust forced me to correctly handle an optional outcome before even getting to an undefined situation.
