You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: modal.rs
    path of file: ./repos/universal-android-debloater/src/gui/widgets
    
    the code of the file until where you have to start completion: use iced_native::alignment::Alignment;
use iced_native::widget::{self, Tree};
use iced_native::{
    event, layout, mouse, overlay, renderer, Clipboard, Color, Element, Event, Layout, Lengt
    
    fn layout(&self, renderer: &Renderer, _bounds: Size, position: Point) -> layout::Node {
        let limits = layout::Limits::new(Size::ZERO, self.size)
            .width(Length::Fill)
            .height(Length::Fill);

        let mut child = self.content.as_widget().layout(renderer, &limits);
        child.align(Alignment::Center, Alignment::Center, limits.max());

        let mut node = layout::Node::with_children(self.size, vec![child]);
        node.move_to(position);

        node
    }
