Function layout_and_apply 

pub fn layout_and_apply<T>(
    treeize: &mut Treeize<T>,
    config: LayoutConfig,
    has_output: impl FnMut(NodeId) -> bool,
    has_input: impl FnMut(NodeId) -> bool,
    node_sizes: Option<&HashMap<NodeId, Vec2>>,
)

Convenience function that performs layout and applies it in one step.

Arguments

• treeize - The tree graph to layout and update
• config - Layout configuration parameters
• has_output - Function to check if a node has output pins
• has_input - Function to check if a node has input pins
• node_sizes - Optional map from node ID to node size (width, height). If provided, the layout will consider actual node sizes to avoid overlaps.

Example

use egui_treeize::{Treeize, layout::{LayoutConfig, layout_and_apply}};
use std::collections::HashMap;

struct MyNode;

let mut treeize = Treeize::<MyNode>::new();
let config = LayoutConfig {
    horizontal_spacing: 200.0,
    vertical_spacing: 150.0,
    start_pos: egui::pos2(0.0, 0.0),
};

// Optional: provide node sizes
let mut node_sizes = HashMap::new();
// node_sizes.insert(node_id, egui::vec2(100.0, 50.0));

layout_and_apply(
    &mut treeize,
    config,
    |node_id| {
        // Check if node has output pins
        let node = &treeize[node_id];
        // Your logic here
        true
    },
    |node_id| {
        // Check if node has input pins
        let node = &treeize[node_id];
        // Your logic here
        true
    },
    Some(&node_sizes),  // or None to ignore sizes
);
