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

Rust Error Handling and Rust in General is still a big black box for me yet to be unveiled :D

Conceptually, error handling in Rust is incredibly simple: if a function can fail, its return type is an enum of either the result of the function (in case of success) or a description of the error that happened. This enum is called Result. See:

why do i need crates for error handling?

You don't. You can 100% handle errors without any additional dependencies, and probably you should be doing that in the beginning. The crates simply add a little bit of syntactic sugar to simplify some boilerplate that you'll have to start writing as soon as your error handling gets sufficiently complex.

I see, maybe i'm still not familiar with it. I'll explore more about error handling in rust later.

Thank you for the pointer.

For the crates, basically its a wrapper i presume? To remove the boiler plate right?
