Create a linked list in Rust: The RC smart pointer

Here, I implement a linked list in Rust utilizing the RC smart pointer. You will learn about the linked list data structure as well as the Box and RC smart pointers in Rust.
There are many other things to learn here, such as the Iterator trait, setting up a test in Rust, and much more.
You can get the code used in this video at github.com/cudidotdev/linked-...

Hey good video, you're doing a great job

[@cudidotdev]

Thank you. This means a lot to me

Very nice content

Thanks for the nice comments 💙

Shouldn't pop return the element it pops off the list?

[@cudidotdev]

You are right. But after removing the element, nothing points to it, so it's dropped. It would be easier if the elements implement the clone trait. I had to do a general case scenario without using any unsafe block

[@nordgaren2358]

@@cudidotdev why not return the RC. Would that work? I'm not at my PC right now.
Liked list is an interesting problem in Rust for sure! I think you did a decent job at tackling it. :)

[@cudidotdev]

I think so. You can try and let me know

@@cudidotdevI think the best way is to do the if let Some on &self.head.take(). This way, you will get ownership of the RC. Then you can call &self.head.replace() with the value obtained by calling next.

@@LtdJorge I will try that and see
