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: page.rs
    path of file: ./repos/youtube-tui/src/global/structs
    
    the code of the file until where you have to start completion: use std::fmt::Debug;

use crate::config::*;
use tui_additions::framework::Framework;
use typemap::Key;

// Page can be converted into PageConfig, which can then be converted into State
/// Covers all possible pages and variants
#[derive(Clone, PartialEq, Eq)]
pub enum Page {
    MainMenu(MainMenuPage),
    // Option<new channel selected
    
    fn fmt(&self, f: &mut std::fmt::Formatter<'_>) -> std::fmt::Result {
        f.write_fmt(format_args!(
            "{}(_)",
            match self {
                Self::MainMenu(_) => "MainMenu",
                Self::Feed => "Feed",
                Self::Search(_) => "Search",
                Self::SingleItem(_) => "SingleItem",
                Self::ChannelDisplay(_) => "ChannelDisplay",
            }
        ))
    }
