Detailed Description

template<typename T, typename Alloc = std::allocator<T>>
class TVAlloc< T, Alloc >

Allocator adaptor that intercepts the 'construct' calls to convert value initialization into default initialization. Written by Casey Carter (@codercasey) Taken from https://hackingcpp.com/cpp/recipe/uninitialized_numeric_array.html.

This allows "std::vector<T>(30)" to only allocate, not initialize, the data.
