template<typename X>
struct maxon::ParameterPack< T >::IndexOf< X >
IndexOf finds the index of type X in the parameter pack T. The index can be found in the member value of IndexOf. If there is no unique such index because X doesn't exist at all in T or exists more than once, a negative value is used. The member found counts the number of occurrences.
