Struct GraphViewState 

pub struct GraphViewState {
    pub model: GraphModel,
    pub decorations: Decorations,
    pub selected: Option<String>,
    pub pan_x: f32,
    pub pan_y: f32,
    pub zoom: f32,
}

The complete observable state (FC-1 / FC-3) of a DecoratedGraphView, in one serializable, round-trippable struct: the laid-out GraphModel, the caller-supplied Decorations overlay, the selected node (keyed on its stable id, FC-5), and the camera (pan + zoom). DecoratedGraphView::state hands back a &GraphViewState; a headless driver (facett_core::harness) snapshots it after feeding a Vec<Msg>.

Fields

model: GraphModel

The graph to paint (nodes laid out in world space + edges).

decorations: Decorations

The caller-supplied ring/badge + emphasis-edge overlay.

selected: Option<String>

The selected node id, if any (lights its downstream subtree).

pan_x: f32

Camera pan (screen-space) — the x component.

pan_y: f32

Camera pan (screen-space) — the y component.

zoom: f32

Camera zoom (world→screen scale), clamped to [0.25, 4.0] by interaction.
