Struct TreeNode 

pub struct TreeNode { /* private fields */ }

A node system that will display as a tree in the terminal using unicode characters. Originally designed to display the Abstract Syntax Tree of my Programming language.

Example:

use cli_tree::TreeNode;

// This will print:
// Test Node
//  ├─Child 1
//  ├─Child 2
//  │ ├─Child 2.1
//  │ ├─Child 2.2
//  │ ├─Child 2.3
//  │ │ ├─Child 2.3.1
//  │ │ └─Child 2.3.2
//  │ └─Child 2.4
//  │   ├─Child 2.4.1
//  │   ├─Child 2.4.2
//  │   └─Child 2.4.3
//  └─Child 3

let mut node = TreeNode::new("Test Node");
// add a single child
node.add_child(TreeNode::new("Child 1"));
// add a child with children which also have children
node.add_child(TreeNode::new_with_children("Child 2",
               vec![TreeNode::new("Child 2.1"),
                    TreeNode::new("Child 2.2"),
                    TreeNode::new_with_children("Child 2.3",
                                  vec![TreeNode::new("Child 2.3.1"),
                                       TreeNode::new("Child 2.3.2")]),
                    TreeNode::new_with_children("Child 2.4",
                                  vec![TreeNode::new("Child 2.4.1"),
                                       TreeNode::new("Child 2.4.2"),
                                       TreeNode::new("Child 2.4.3")])]));
// add another singular child
node.add_child(TreeNode::new("Child 3"));
println!("{}", node);
