Detailed Description

template<typename Derived, std::unsigned_integral T, T Empty>
class v1::tagged_id< Derived, T, Empty >

A tagged identifier.

Template Parameters

Derived	The derived class.
T	The unsigned integer type used as the underlying type.
Empty	The underlying value the means empty. Often either zero or std::numeric_limits<T>::max().
