Struct winit::event_loop::OwnedDisplayHandle

pub struct OwnedDisplayHandle { /* private fields */ }

A proxy for the underlying display handle.

The purpose of this type is to provide a cheaply clonable handle to the underlying display handle. This is often used by graphics APIs to connect to the underlying APIs. It is difficult to keep a handle to the EventLoop type or the ActiveEventLoop type. In contrast, this type involves no lifetimes and can be persisted for as long as needed.

For all platforms, this is one of the following:

• A zero-sized type that is likely optimized out.
• A reference-counted pointer to the underlying type.
