Struct TreeNode 

pub struct TreeNode<T> {
    pub name: String,
    pub data: Option<T>,
    pub children: Vec<TreeNode<T>>,
}

Generic tree node that can hold any data type

Represents a node in a hierarchical tree structure. Each node has a name, optional data, and a list of child nodes.

Fields

name: String

Name of the node (e.g., file name, directory name)

data: Option<T>

Optional data associated with the node (None for directory nodes)

children: Vec<TreeNode<T>>

Child nodes

Implementations

impl<T> TreeNode<T>

pub const fn new(name: String, data: Option<T>) -> Self

Create a new tree node

Arguments

• name - Name of the node
• data - Optional data associated with the node

Examples

use tree_fmt::TreeNode;

// Create a file node with data
let file = TreeNode::new( "main.rs".to_string(), Some( 100u64 ) );

// Create a directory node without data
let dir : TreeNode< u64 > = TreeNode::new( "src".to_string(), None );
