Struct TreeNodeOptions 

pub struct TreeNodeOptions {
    pub style: Option<Style>,
    pub guide_style: Option<Style>,
    pub expanded: Option<bool>,
    pub highlight: Option<bool>,
}

A tree node that can be rendered with guide lines.

Tree is a hierarchical data structure where each node has a label (content) and zero or more children. When rendered, guide lines connect the nodes to show the tree structure.

Example

use rich_rs::{Tree, Text};

let mut root = Tree::new(Box::new(Text::plain("Documents")));
let mut projects = root.add(Box::new(Text::plain("Projects")));
projects.add(Box::new(Text::plain("project1")));
projects.add(Box::new(Text::plain("project2")));
root.add(Box::new(Text::plain("notes.txt")));

Options for adding a child node to a tree.

Used with Tree::add_with_options() to specify per-node overrides.

Fields

style: Option<Style>

Style for this node’s label. If None, inherits from parent.

guide_style: Option<Style>

Style for guide lines from this node. If None, inherits from parent.

expanded: Option<bool>

Whether children are shown. Defaults to true.

highlight: Option<bool>

Whether to apply highlighting. If None, inherits from parent.
