pub fn drop_node_iteratively<T: Terminal, F: Function>(node: TreeNode<T, F>)Expand description
Free a tree node and all of its descendants without deep recursion.
EV-60: TreeNode now has a stack-safe Drop impl, so simply dropping a
node already frees an arbitrarily deep tree iteratively. This helper is
retained as an explicit, self-documenting entry point (and for source
compatibility) but is no longer required to avoid a stack overflow — a plain
drop(node) or letting the node fall out of scope is equally safe.
