Struct CornerInsets 

pub struct CornerInsets {
    pub top_left: CornerInset,
    pub top_right: CornerInset,
    pub bottom_left: CornerInset,
    pub bottom_right: CornerInset,
}

The inset vocabulary LayoutCtx::window_insets/PaintCtx::window_insets return — lifted because a widget that lays itself out around the status bar, notch, or on-screen keyboard cannot otherwise name the value those accessors hand it. A bar laying out around the iPadOS window control names the corner value, CornerInsets. Window-control footprints at the four window corners, in logical pixels.

• Values are logical px (see the module docs).
• Corners are physical: frust has no RTL layout, so the shell resolves direction. In an RTL locale the iPadOS window control lands top-RIGHT.
• Each value is the extent by which a system window control protrudes beyond the safe-area rectangle at that corner: width is measured inward from the safe area’s vertical edge, height inward from its horizontal edge. A widget whose content band starts at the safe-area top therefore overlaps the corner iff height > 0.0 – whether it self-insets the top (reads padding().top) or sits under a top-consuming SafeArea (reads 0) – because in both cases the control’s bottom edge is safe-area-top + height.
• Corners are never consumed and never part of WindowInsets::padding; WindowInsets::consuming leaves them alone.
• Today only the iOS shell reports them (the iPadOS 26+ window control). Android, desktop, web and iOS < 26 leave them zero.
• Accepted gap: a bar that does not consume the horizontal safe-area insets under-shifts for a control on a notched edge (no platform draws one there).
• Bars shift for overlap only when spanning the window’s left/right edges (typical of app bars at the top). Content hosted in a detail pane, sheet, dialog, or below other content still receives the window-wide corner values (corners are never consumed; layout cannot see its window-space origin) and would over-shift. Shipped bars expose corner_shift(false) as the author’s opt-out; no automatic detection exists.
