Tell me to me. I try for several months to build a way around this on rust (ie: Have a generic interface to both columnar and row-oriented layout and "just" switch to optimized operations later). I think is impossible. The closest thing is use a NDArray and pick a winner/default layout... that is row-oriented, despite my intention to be columnar first, and later develop an alternate, complete rewrite, for support columnar.
