public class TypeInfo
extends Record

This structure is used to provide the type system with the information
required to initialize and destruct (finalize) a type's class and
its instances.

The initialized structure is passed to the g_type_register_static() function
(or is copied into the provided #GTypeInfo structure in the
g_type_plugin_complete_type_info()). The type system will perform a deep
copy of this structure, so its memory does not need to be persistent
across invocation of g_type_register_static().
