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: tui.rs
    path of file: ./repos/holochain/crates/holochain_terminal/src
    
    the code of the file until where you have to start completion: use crate::app::App;
use crate::components::bootstrap::render_bootstrap_widget;
use crate::components::network_info::render_network_info_widget;
use crossterm::terminal;
use crossterm::terminal::{EnterAlternateScreen, LeaveAlternateScreen};
use ratatui::backend::Backend;
use ratatui::layout::{Alignment, Constraint};
use ratatui::prelude::{Color, Direction, Layout, Line, Style};
use ratatui::symbols::DOT;
use ratatui::widgets::{Block, Tabs};
use ratatui::{Frame, Terminal};

    pub fn init(&mut self) -> anyhow::Result<()> {
        terminal::enable_raw_mode()?;
        crossterm::execute!(io::stderr(), EnterAlternateScreen)?;

        // Define a custom panic hook to reset the terminal properties.
        // This way, you won't have your terminal messed up if an unexpected error happens.
        let panic_hook = panic::take_hook();
        panic::set_hook(Box::new(move |panic| {
            Self::reset().expect("failed to reset the terminal");
            panic_hook(panic);
        }));

        self.terminal.hide_cursor()?;
        self.terminal.clear()?;
