gust VS classi-cine

This tutorial helped me improve my understanding along with the Book and the docs. In a beginner project I've been working on--a tool to make grocery lists--I've tried to work on my understanding of using Result and the ? operator. Right now I'm using Box in my different functions to pass down error messages to main() in case there's something wrong, and using something like this code snippet to give more helpful errors to a user where necessary: ``` src/lib.rs

I wrote a typical first project type application called grustery-list, which I've been using to put grocery lists together. It updates a library of groceries we regularly buy, a library of recipes we often make, saves a most recent grocery list in case I just want to update a list I made earlier, and prints out a grocery list. I've been using Element to copy and paste my list and send to my phone before we go shopping.
