187/// @brief Macros to help determine whether or not a class has a particular
188/// member function.
189/// @details These macros work by instantiating unique templated instances
190/// of helper structs for a particular member function signature and name
191/// which can then be queried.
192/// - The first macro, INVOKABLE, defines a helper struct which determines
193/// if a member function can be called with a given set of argument types.
194/// Note that the return type is not provided.
195/// - The second macro defines a helper struct which determines if the
196/// member function exists with the _exact_ same signature, including
197/// all argument and function attributes (const-ness, noexcept, etc)
198///
199/// Use the first solution if all you want to determine is whether a given
200/// method can be called, and the second if you need exact resolution.
201/// @code
202/// // example class
203/// struct MyClass { int test(double) { return 0; } };
204///
205/// // The following examples work from the struct type created by:
206/// OPENVDB_INIT_INVOKABLE_MEMBER_FUNCTION(test);
207///
208/// // Will assert true!
209/// static_assert(OPENVDB_HAS_INVOKABLE_MEMBER_FUNCTION(MyClass, test, double));
210/// // Will assert true, int can be converted to double
211/// static_assert(OPENVDB_HAS_INVOKABLE_MEMBER_FUNCTION(MyClass, test, int));
212/// // Will assert false, needs at least one argument
213/// static_assert(OPENVDB_HAS_INVOKABLE_MEMBER_FUNCTION(MyClass, test);

272/// @brief Re-implementation of C++17's index_sequence and the helper alias
273/// make_index_sequence. This was introduced to fix an issue with clang's
274/// builtin implementation which treats template specializations of builtin
275/// templates differently when a subsequent parameter is dependent. The
276/// result is a resolution failure during partial specialization selection.
277/// For example, the following will fail to specialize:
278///
279/// @code
280/// struct Test { static const int VALUE = 1; };
281///
282/// template <typename T, typename S = std::make_index_sequence<T::VALUE>>

284/// template <typename T> struct Adapter {};
285/// template <typename T> struct Adapter<Item<T>> {}; // FAIL: will never be selected.
