Struct NodeState 

pub struct NodeState {
    pub is_selected: bool,
    pub is_expanded: bool,
    pub level: usize,
    pub has_children: bool,
    pub path: Vec<usize>,
}

State information for rendering a node.

Provides context about a node’s current state during rendering, allowing the render function to customize the display based on selection, expansion, and position in the tree.

Example

use ratatui_toolkit::tree_view::NodeState;

let state = NodeState {
    is_selected: true,
    is_expanded: false,
    level: 0,
    has_children: true,
    path: vec![0],
};

Fields

is_selected: bool

Whether this node is selected

is_expanded: bool

Whether this node is expanded

level: usize

Depth level in the tree (0 = root)

has_children: bool

Whether this node has children

path: Vec<usize>

Path to this node (indices from root)
