Struct WindowMetrics 

pub struct WindowMetrics {
    pub size: Size,
    pub scale: f64,
    pub orientation: Orientation,
    pub insets: WindowInsets,
}

The window-shape value recovered via use_context::<WindowMetrics>() inside Component::build — lifted alongside WindowInsets for the same reason: a widget or component laying itself out around window size/scale/orientation cannot otherwise name the value. See WindowMetrics’s own doc for the plain-value delivery contract, the alongside-not-superseding relationship with WindowInsets, and the derived-orientation/rebuild-cost notes. The window’s logical size, device-pixel scale, derived Orientation and WindowInsets, as a plain provide_context value: use_context subscribes to nothing, so a changed value is visible only on the next rebuild. Re-provide it only on change, beside the standalone insets.

Fields

size: Size

The window’s logical (density-independent) size.

scale: f64

The device-pixel scale factor (logical → physical px multiplier).

orientation: Orientation

Derived from size; no platform callback carries an orientation.

insets: WindowInsets
