No, this is not a post about how to implement doubly linked list in rust.

Or ir could be a very short post, since doubly linked list in built-in the std::collection as LinkedList

Following functions are available:

• new : Creates new/empty linked list
• push_back : Adds an element to the list
• push_front : Since this is doubly linked list, element can be added at the beginning as well. Nice!
• pop_back and pop_front : Remove an element from the list
• clear : empty the entire list
• append : Append one list to another to make bigger list. One that got appended becomes empty though.
• contains : Searches through the list for the element ¹
• There are iter, iter_mut and len as well.

[Documentation](https://doc.rust-lang.org/std/collections/ struct.LinkedList.html) is easy to understand
