pub fn export_measure_csv(
model: &Model,
measure: MeasureId,
path: &Path,
delimiter: u8,
) -> Result<usize>Expand description
Write a measure’s cells to a CSV/TSV file: one column per dimension
category (item name) plus a value column, header row first. An input
measure exports its stored cells; a derived measure is evaluated by the
engine and exports its computed cells (IMPROV.txt:113 — export the computed
view). Returns the number of rows written. See export_measure_csv_to
for the writer-based (testable) version.
