Source 
pub fn columnar_exchange_data<D, T, R>((d, _, _): &Ref<'_, (D, T, R)>) -> u64
where
    D: Columnar,
    for<'a> Ref<'a, D>: Hash,
    T: Columnar,
    R: Columnar,
Expand description

Routes a (D, T, R) column by the hash of its data column.

Counterpart to columnar_exchange for collections whose data is not a key/value pair. Consolidation sites want columnar_consolidate_exchange instead.
