Detailed Description

Functor that maps an ArrayIndex into linear numbers, where the fast moving index should be the rightmost one, which models how C++ arrays work and is analogous to mdspan's layout_right. E.g. ArrayIndex<3> a; stores 3 indices where a[2] should be incremented in the innermost loop.
