Detailed Description

template<typename Elem, typename = void>
struct mf::masked_elem< Elem, typename >

Nullable wrapper for elem type which adds mask.

POD type, where the elem is always at same memory address as the masked_elem object. A one byte mask is added behind the element. Depending in alignmment requirement of Elem, sizeof(masked_elem<Elem>) can become larger than sizeof(Elem) + 1.
