Stacking

stacking is a module containing tools for building stacks in rust

Stack

stacking comes with a Stack builtin. It only supports pop, push and len as actions

Examples

```rust use stacking::stacks::Stack;

let mut stack: Stack = Stack::new(); asserteq!(stack.len(), 0); stack.push(4); asserteq!(stack.len(), 1); assert_eq!(stack.pop(), Some(4)); ```

This simple example creates a stack, appends 4 to it and pops it off again.

Nodes

stacking also contains a Node. A Node can be used to build custom stacks or other data structures with specific orders.

Examples

```rust use stacking::nodes::Node;

let mut n1: Node = Node::new(None, None, 15); let mut n2: Node = Node::new(None, Some(n1.clone()), 14); asserteq!(n1.val, 15); asserteq!(n2.val, 14); ```

This will create two nodes referencing each other to create an order in which after n2 comes n1.
