-// TreeOperator is an interface for performing basic btree operations.
-type TreeOperator interface {
-	// TreeWalk walks a tree, triggering callbacks for every node,
-	// key-pointer, and item; as well as for any errors encountered.
-	//
-	// If the tree is valid, then everything is walked in key-order; but
-	// if the tree is broken, then ordering is not guaranteed.
-	//
-	// Canceling the Context causes TreeWalk to return early; no values
-	// from the Context are used.
-	//
-	// The lifecycle of callbacks is:
-	//
-	//	000  (read superblock) (maybe cbs.BadSuperblock())
-	//
-	//	001  (read node)
-	//	002  cbs.Node() or cbs.BadNode()
-	//	     if interior:
-	//	       for kp in node.items:
-	//	003a     if cbs.PreKeyPointer == nil || cbs.PreKeyPointer() {
-	//	004b       (recurse)
-	//	     else:
-	//	       for item in node.items:
-	//	003b     cbs.Item() or cbs.BadItem()

-	// returned.
