fn keyed_corners<T>(
waypoints: &[Waypoint],
value: impl Fn(&Waypoint) -> T,
) -> Vec<(Option<PathOrdinal>, T)>Expand description
The stored corners as a working list keyed by the ordinal each holds in
the document. Shared by the plan and its replay rather than written twice:
both count positions in this list, and a list built two ways is two
different meanings for the same InsertAt.
