C++03
template <typename T>
explicit packet(const T& value)

C++11
template <typename T>
explicit packet(T&& value)

Constructs an object of type T with the supplied value.
Static asserts on any type that does not derive from TBase.
Static asserts on any type that does not conform to the maximum size and alignment.

Destructor

~packet()

Destructs the contained object
