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: debugger.rs
    path of file: ./repos/game-dev-with-rust/garbage/dragon-fighter/src/system
    
    the code of the file until where you have to start completion: use crate::system::player::Player;
use crate::App;
use bevy::prelude::Plugin;
use bevy_inspector_egui::{RegisterInspectable, WorldIns
    
    fn build(&self, app: &mut App) {
        // Debug modda çalışıyorsak debug etmemizi kolaylaştıran plug-in'i uygulamaya ekliyoruz
        // Ayrıca izlemek istediğimiz Player nesnesini de burada bildiriyoruz
        if cfg!(debug_assertions) {
            app.add_plugin(WorldInspectorPlugin::new())
                .register_inspectable::<Player>();
        }
    }
