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: mod.rs
    path of file: ./repos/cacao/src/uikit/app
    
    the code of the file until where you have to start completion: //! Wraps the application lifecycle across platforms.
//!
//! This is where the bulk of your application logic starts out from. macOS and iOS are driven
//! heavily by lifecycle events - in this case, your boilerplate would look something like this:
//!
//! ```rust,no_run
//! use cacao::ios::app::{App, AppDelegate};
//! use cacao::win
    
    pub fn run(&self) {
        let args = std::env::args()
            .map(|arg| CString::new(arg).unwrap())
            .collect::<Vec<CString>>();

        let c_args = args.iter().map(|arg| arg.as_ptr()).collect::<Vec<*const c_char>>();

        let cls = register_app_class();
        let dl = register_app_delegate_class::<T>();

        let cls_name: id = unsafe { msg_send![cls, className] };
        let dl_name: id = unsafe { msg_send![dl, className] };

        unsafe {
            UIApplicationMain(c_args.len() as c_int, c_args.as_ptr(), cls_name, dl_name);
        }

        //self.pool.drain();
    }
