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: main.rs
    path of file: ./repos/nyaa/src
    
    the code of the file until where you have to start completion: use std::{env, io::stdout};

use app::{run_app, App};
use crossterm::{
    cursor::SetCursorStyle,
    terminal::{disable_raw_mode, enable_raw_mode, EnterAlternateScreen, LeaveAlternateScreen},
    ExecutableCommand,
};
use ratatui::{backend::CrosstermBackend, Terminal};

mod app;
mod client;
mod config;
mod source;
mod widget;

#[tokio::main()]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // TODO: Use real command li
    
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // TODO: Use real command line package
    let args: Vec<String> = env::args().collect();
    for arg in args {
        if arg == "--version" || arg == "-V" || arg == "-v" {
            println!(
                "nyaa v{}",
                option_env!("CARGO_PKG_VERSION").unwrap_or("UNKNOWN")
            );
            return Ok(());
        }
    }
    enable_raw_mode()?;
    stdout().execute(EnterAlternateScreen)?;
    stdout().execute(SetCursorStyle::SteadyBar)?;
    let backend = CrosstermBackend::new(stdout());
    let mut terminal = Terminal::new(backend)?;

    let mut app = App::default();

    run_app(&mut terminal, &mut app).await?;

    disable_raw_mode()?;
    stdout().execute(SetCursorStyle::DefaultUserShape)?;
    stdout().execute(LeaveAlternateScreen)?;
    terminal.show_cursor()?;

    Ok(())
