Rust Beginners Challenge - Check in - Write a file diff program [PROJECT]

Intro

Not long ago I posed a challenge for those of us learning rust: https://lemmy.ml/post/12478167.

Basically write an equivalent of git diff --no-index A B … a file differ.

While it’s never too late to attempt it, I figured it’d be a good time to check in to see what anyone thought of it, in part because some people may have forgotten about it and would still like to have a shot, and also because I had a shot and am happy with what I wrote.

Check In

I’ll post where I got up to below (probably as a comment), but before that, does anyone have anything to share on where they got up to … any general thoughts on the challenge and the general idea of these?

My experience

My personal experience was that I’d not kept up with my rust “studies” for a bit and used this as a good “warm up” or “restart” exercise and it worked really well. Obviously learning through doing is a good idea, and the Rust Book is a bit too light, IMO, on good exercises or similar activities. But I found this challenge just difficult enough to make me feel more comfortable with the language.

Future Challenges

Any ideas for future challenges??

My quick thoughts

A simple web app like a todo app using axtix_web and diesel and some templating crate.
Extend my diffing program to output JSON/HTML and then to diff by characters in a string
A markdown parser??

Welcome

A collaborative space for people to work together on learning Rust, learning about the Lemmy code base, discussing whatever confusions or difficulties we’re having in these endeavours, and solving problems, including, hopefully, some contributions back to the Lemmy code base.

Rules TL;DR: Be nice, constructive, and focus on learning and working together on understanding Rust and Lemmy.

Policies and Purposes

This is a place to learn and work together.

Questions and curiosity is welcome and encouraged.

This isn’t a technical support community. Those with technical knowledge and experienced aren’t obliged to help, though such is very welcome. This is closer to a library of study groups than stackoverflow. Though, forming a repository of useful information would be a good side effect.

This isn’t an issue tracker for Lemmy (or Rust) or a place for suggestions. Instead, it’s where the nature of an issue, what possible solutions might exist and how they could be or were implemented can be discussed, or, where the means by which a particular suggestion could be implemented is discussed.
