fn values_for(
model: &Model,
measure: MeasureId,
snapshot: &Snapshot,
) -> HashMap<CoordKey, CellValue>Expand description
The value map for a measure: CoordKey -> CellValue.
Input measures read straight from model.inputs; derived measures come from
the live engine snapshot (empty map -> grid renders blank). Values keep
their type so the grid can render numbers, text, booleans, dates, and #ERR.
