Struct MetroState 

pub struct MetroState {
    pub map: MetroMap,
    pub selected: Option<String>,
}

The complete observable state (FC-1 / FC-3) of a MetroView, in one serializable, round-trippable struct: the whole drawn MetroMap plus the drilled-in selection (keyed on the line id, FC-5). MetroView::state hands back a &MetroState; a headless driver (facett_core::harness) snapshots it after feeding a Vec<Msg>.

Fields

map: MetroMap

Every chain as a line — the whole drawn map.

selected: Option<String>

Selected line id (for a host’s drill-in), if any.
