Struct NodeView 

#[non_exhaustive]
pub struct NodeView<'s> {
    pub id: Option<usize>,
    pub dummy_of: Option<(usize, usize)>,
    pub x: usize,
    pub y: usize,
    pub width: usize,
    pub height: usize,
    pub kind: NodeKind,
    pub label: &'s str,
    pub content: NodeKindTag,
    pub payload: Option<&'s str>,
}

One node of the scene.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

id: Option<usize>

Graph id — None for dummies: their raw ids are synthetic and backend-specific, so the scene never exposes them. Dummies carry dummy_of instead.

dummy_of: Option<(usize, usize)>

Backend-stable dummy identity: the owning edge’s INPUT index (the style-callback / EdgeView::input_index convention) and the level the dummy occupies — the same pair HitResult::Dummy reports. None for real nodes.

x: usize

Left edge, in cells.

y: usize

Top edge, in rows.

width: usize

Width in cells (including brackets/padding).

height: usize

Height in rows.

kind: NodeKind

Real-vs-dummy dichotomy.

label: &'s str

Label text (empty for dummies).

content: NodeKindTag

Declared content kind (simple / boxed / custom).

payload: Option<&'s str>

Custom-node payload — the data half of the template/data pair, rejoined by the scene (“geometry and keyed content meet again here”). None when the node declared no custom content.
