LRU Cache (doubly linked list) with Rust

Hi Rustaceans!

I decided to tackle learning rust over the weekend. Mostly to play with the Bevy Game Engine.

To prepare myself and sharpen my skills, I decided to do some leetcode programming exercises. This is where things started to go south.

One of the first exercises I attempted was to do a doubly linked list for an LRU cache and I ran straight into this article

Is the standard way to handle graphs, dags, and doubly linked lists simply to use libs? To use unsafe rust? Is this an area that Rust makes things complicated?
