Enum WindowVisibility 

pub enum WindowVisibility {
    Visible,
    Hidden,
}

Whether the platform is presenting a window’s frames.

This is about presentation, not the window’s shown/hidden state: a shown window that is fully covered by other windows, minimized, on another Space or virtual desktop, or on a display that is asleep is Hidden. A window only partly covered by other windows is Visible.

Each platform reports from a single source, and what that source can see differs:

• macOS: NSWindow.occlusionState. Covers all of the cases above.
• Windows: WS_VISIBLE and the minimized state. Windows keeps compositing covered windows for thumbnails and Alt-Tab and offers no occlusion notification, so a fully covered window stays Visible. Display sleep is not reported either.
• Wayland: the xdg_toplevel suspended state (xdg-shell v6). Compositors that don’t support it never report Hidden.
• X11: mapped state plus VisibilityNotify. Compositing window managers generally never report a window as fully obscured, so covering is only detected without compositing.

Variants

Visible

At least part of the window is being presented; frames drawn for it will be shown.

Hidden

No part of the window is being presented. The platform will not request frames for it until it becomes visible again.
