Struct AnchorRect 

pub struct AnchorRect {
    pub x: f64,
    pub y: f64,
    pub width: f64,
    pub height: f64,
}

A rectangle in logical points of the presenting window’s coordinate space, origin top-left — where an action sheet’s popover points from.

Getting one

frust’s logical pixels are view points on iOS (frust-shell-ios’s touch/IME contract: logical points pass through with no scale division), and the default shell’s frust view fills its window, so any rect frust reports in window space is already an anchor, unconverted:

• A native control’s slot — the rect a platform_view slot publishes each paint (PlatformViewFrame::rect, the absolute painted rect the platform view is positioned from) is exactly where the control sits; anchor a “more actions” sheet on the button that opened it.
• A frust widget — its window-space rect: an overlay surface’s window_rect(), or the origin a layout you control accumulates down to the widget plus its size.
• A point — a zero-size rect at a tap location (the popover arrow points at the point).

The iOS arm converts it into the presenting controller’s view with convertRect:fromView:nil (window base coordinates), so it also holds when that controller’s view is not full-window (a form sheet). A rect outside the window is passed to UIKit as-is; UIKit clamps the popover onto the screen.
