Struct ObjectGeometry 

pub struct ObjectGeometry {
    pub kind: &'static str,
    pub bbox: Option<(f64, f64, f64, f64)>,
}

Per-shape geometry for the JSON objects export. bbox is in SVG user units — the same space as the root viewBox and the <g id="sN"> groups — so editors can hit-test without touching the DOM. None when the shape draws nothing (e.g. invis), though its sN group still exists.

Fields

kind: &'static str

Shape kind as a stable lowercase name (box, circle, …).

bbox: Option<(f64, f64, f64, f64)>

(x, y, w, h) of the shape’s bounds in SVG user units.
