Learning about "take" with a Linked List example | Rust Language

I share Some of the things I learned from studying how to do a Linked List in Rust, especially using the "take()" method. The idea was to learn how to manipulate the structs and struct data contained within the Nodes of the Linked List. In summary, this was to practice using Box, Option, and Generic type T as much as possible. Note I think of "next" as "previous" mainly due to learning about the Bitcoin nettwork which uses "previous blockhash" - my bad!

Here are some notes on the "length" function that checks how many nodes are in the list :

Since the dawn of time the pointer to the next node in a linked list has been called "next". No confusion there.

Thank you.
I think maybe I've been tinkering with Bitcoin nodes too much, where there is a "previous block"
