Struct Element 

pub struct Element {
    pub id: u64,
    pub kind: ElementKind,
    pub stroke: Option<u32>,
    pub fill: Option<u32>,
    pub label: Option<String>,
    pub label_color: Option<u32>,
    pub styles: Vec<StyleSpan>,
    pub mindmap: Option<MindMapNodeMeta>,
}

One board element: a stable id plus its geometry/kind.

Fields

id: u64

kind: ElementKind

stroke: Option<u32>

Stroke / ink color, packed 0xRRGGBBAA. None follows the theme ink, so uncolored elements still adapt to light/dark. Absent in older boards → 0.

fill: Option<u32>

Fill color for closed shapes (rect/ellipse), packed 0xRRGGBBAA. None is an unfilled outline. Ignored by other kinds. Absent in older boards.

label: Option<String>

Centered text label for closed shapes (rect / ellipse / …). Rendered at a font size auto-shrunk so the wrapped text never crosses the shape’s border (see the shape paint path). None / empty = no label; ignored by non-shape kinds. Absent in older boards → None.

label_color: Option<u32>

Color of the shape’s label, packed 0xRRGGBBAA. None inks it with the shape’s stroke (theme ink if that’s unset too). Ignored by non-shape kinds. Absent in older boards → None.

styles: Vec<StyleSpan>

Rich-text formatting runs over the element’s text (a Text element’s content, or a shape’s label): bold / italic / underline / strikethrough / highlight, each over a byte range. Empty = unstyled. Kept sorted + non-overlapping and maintained across edits; absent in older boards.

mindmap: Option<MindMapNodeMeta>

Optional whiteboard-native mind-map metadata. Only mind-map nodes carry this; lines stay regular anchored arrows.
