Feedback for first Rust Program (codeberg.org)

Hello

I've been interested with Rust for the last year, but cannot find time to learn Rust.

Coming from Python, i have found my self quite difficult to learn Rust and grasp its concepts.

So, for the last couple of weeks, i have been able to spare some times to learn Rust, and created a mini project to parse Vendor OUI with Rust.

If you would be so kind to spare some of your time to review my code and give me some constructive feedback on how to tackle this, and some guidance for me about what i can improve because its not the rust way of doing things, i would be very happy. I want to improve my skills on Rust so i have another tools in my toolbox

This is not a promotion, because i believe there's another tools just like mine out there nor i want you to use my project, because this project is only for me to test my skill for using Rust.

Thank you in advanced :D

Thank you for those who reply, i really learned something new. I'll try to improve my code :D

This is a pet peeve of mine, but don't put main last. Its like opening a book to be greeted by a random chapter - probably one near the end and you have to hunt through it to find where the story actually starts, which is probably near the end.

This is a IMO horribly hangup from languages that require you to declare something before you can use it. You don't need to do that in rust. So put your functions in order that makes sense to read them from top to bottom. This typically means main should be one of the first functions you see - as it is the entry point to the code. In other files this might be the main functions a user is expected to use first. Sometimes you might want to see some datastructures before that. But overall things should be ordered by how it makes sense to read them to make it easier to make sense of the program.

Hello, nous.

Thank you for your feedback. I just know today that in rust, you can do this. I do agree with you about how to order things so it can convey more meaning to the reader. I'll keep that in mind in my next iterations.

Thank you
