-- 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 'GI.GObject.Functions.typeRegisterStatic' function
-- (or is copied into the provided t'GI.GObject.Structs.TypeInfo.TypeInfo' structure in the
-- 'GI.GObject.Interfaces.TypePlugin.typePluginCompleteTypeInfo'). The type system will perform a deep
-- copy of this structure, so its memory does not need to be persistent
-- across invocation of 'GI.GObject.Functions.typeRegisterStatic'.
