* The correct serialization or deserialization function is chosen at

* This function can be used to serialize a trivial copy-able type or a

* The right template to be called is determined in the function itself.
* For objects of non trivial copy-able type this function is almost never called by the user directly.
* Instead helpers for specific types like SerialArrayListAdapter or SerialLinkedListAdapter is the right choice here.

* @param[in] object Object to serialize, the used type is deduced from this pointer
* @param[in/out] buffer Buffer to serialize into. Will be moved by the function.
