Detailed Description

template<typename... T>
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.

ParameterPack<Int, Float, String, String>::IndexOf<Float>::value == 1
ParameterPack<Int, Float, String, String>::IndexOf<String>::value < 0 // Ambiguous.
ParameterPack<Int, Float, String, String>::IndexOf<String>::found == 2
ParameterPack<Int, Float, String, String>::IndexOf<Char>::value < 0 // Not found.
