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: runner.rs
    path of file: ./repos/winit/src/platform_impl/windows/event_loop
    
    the code of the file until where you have to start completion: use std::{
    any::Any,
    cell::{Cell, RefCell},
    collections::VecDeque,
    mem, panic,
    rc::Rc,
    sync::{Arc, Mutex},
    time::Instant,
};

use windows_sys::Win32::Foundation::HWND;

use crate::{
    dpi::PhysicalSize,
    event::{Event, InnerSizeWriter, StartCause, WindowEvent},
    platform_impl::platform::{
        event_loop::{WindowData, GWL_USERDATA},
        get_window_long,
    },
    window::WindowId,
};

use super::ControlFlow;

pub(crate) type EventLoopRunnerShared<T> = Rc<EventLoopRunner<T>>;

type EventHandler<T> = Cell<Option<Box<dyn FnM
    
    fn dispatch_buffered_events(&self) {
        loop {
            // We do this instead of using a `while let` loop because if we use a `while let`
            // loop the reference returned `borrow_mut()` doesn't get dropped until the end
            // of the loop's body and attempts to add events to the event buffer while in
            // `process_event` will fail.
            let buffered_event_opt = self.event_buffer.borrow_mut().pop_front();
            match buffered_event_opt {
                Some(e) => e.dispatch_event(|e| self.call_event_handler(e)),
                None => break,
            }
        }
    }
