Struct MediaLibraryChangeStream 

pub struct MediaLibraryChangeStream { /* private fields */ }

Available on crate feature async only.

Stream of NotificationEvents fired when the media library changes.

Wraps MPMediaLibraryDidChangeNotification.

macOS note: MPMediaLibrary is iOS/tvOS-only so this notification never fires on macOS; the stream will be open but idle.
