Ase::AlignedPOD

struct Ase::AlignedPOD

template<size_t SIZE>
struct Ase::AlignedPOD< SIZE >

Helper to provide memory for placement new AlignedPOD<SIZE> is aligned like max_align_t or like malloc()-ed memory and provides SIZE bytes.

Idiomatic use is:

static AlignedPOD<sizeof (std::string)> pod_mem;
std::string *str = new (&pod_mem) std::string();
