Thanks for your detailed reply. I can feel I’m out of my depth in many ways, but between your reply and the others I’ve gotten, I have a lot of entryways into the problem, and I’m looking forward to figuring out how to make it work. I’ve done a bit of coding in C++ in the past as well; maybe that would also be an option. But since the purpose of the exercise is primarily to get more familiar with Rust, I think I’ll exhaust whatever options I have down that path first. Thanks again :)
I don’t understand the purpose of Spotify posting a complete work of fiction like this. There’s nothing random about their Shuffle setting, nothing at all. There’s a reason third-party sites that serve no other purpose than to shuffle Spotify playlists exist.
