Thank you for creating this playlist; these are easy to understand examples. Would you consider creating a real world application using all these concepts?
Thank you! Yes, I would certainly consider creating a full application. I'm focusing on the core concepts of Rust for now, but once we cover most of those, I'll create some practical Rust applications! Rust on! 🦀🦀
That's an excellent question. I believe the simplest answer is that the .remove() method signature requires a borrow of the underlying key type. In this case, my HashMap key was of type String, so in order to satisfy the method signature, I had to use &String. That is essentially what the documentation says here doc.rust-lang.org/stable/std/collections/struct.HashMap.html#method.remove
