Crate tree_iter

Tree-Iter

A Rust library for iterating over tree structures in different traversal orders.

This library provides traits and implementations for efficient iteration over tree-like data structures in both breadth-first and depth-first traversal orders, with support for both immutable and mutable traversal.

Features

• Generic support for any tree-like structure
• Breadth-first and depth-first traversal orders
• Immutable and mutable iteration
• Safe interior mutability during traversal using guard patterns

Example

use tree_iter::prelude::*;
use tree_iter::tree::Node;

// Create a simple tree
let tree = Node {
    value: 1,
    children: vec![Node::new(2), Node::new(3)],
};

// Iterate over the tree in depth-first order
let values: Vec<i32> = tree.iter::<DepthFirst>()
                          .map(|node| node.value)
                          .collect();
assert_eq!(values, vec![1, 2, 3]);
