Structures

Allows recursively referencing a struct within itself.

struct Node {
   // MARK: - Public Properties
   let id: Int

   var left: Node {
       self._left.value
   }
   var right: Node {
       self._right.value
   }

   // MARK: - Private Properties
   private let _left: IndirectReference<Node>
   private let _right: IndirectReference<Node>
}
