Macro Definition Documentation

MEMVIZ_REGISTER

#define MEMVIZ_REGISTER	(		Type,
			Tuple
	)

Value:

    namespace memviz {                                   \
    template <> struct MemberInfo<Type> {                \
        using type = decltype(Tuple);                    \
        static constexpr auto get() { return Tuple; }    \
    };                                                   \
    }

Registers a user-defined type for reflection in MemViz.

This macro specializes the memviz::MemberInfo<T> struct for the given type Type, enabling compile-time reflection over its member variables.

The macro should be used in the same translation unit where the type is visible, and before any calls to dumpLayout<T>() or getMembers<T>().

Parameters

Type	The type (class/struct) to register.
Tuple	A std::tuple containing std::pair<const char*, T member_ptr> for each field.

Note

This macro must be used at global scope.

Requires C++20 support for structured bindings and templates.
