//! Types useful for interacting with a user's monitors.
//!
//! If you want to get basic information about a monitor, you can use the [`MonitorHandle`][monitor_id]
//! type. This is retreived from an [`AvailableMonitorsIter`][monitor_iter], which can be acquired
//! with:
//! type. This is retreived from one of the following methods, which return an iterator of
//! [`MonitorHandle`][monitor_id]:
//! - [`EventLoop::available_monitors`][loop_get]
//! - [`Window::available_monitors`][window_get].
//!
//! [monitor_id]: ./struct.MonitorHandle.html
//! [monitor_iter]: ./struct.AvailableMonitorsIter.html
//! [loop_get]: ../event_loop/struct.EventLoop.html#method.available_monitors
//! [window_get]: ../window/struct.Window.html#method.available_monitors
