This transformation implements the funcionality specified by the LazilyGenerated metadata item. In short, this transformation will remove any unreferenced record declarations marked with LazilyGenerated.
Anonymous structs, classes, and unions from C++ are always marked with LazilyGenerated. You can use LazilyGenerated in conjunction with this transformation to remove any uneeded types from your library. For example, you might mark all declarations from a specific internal header file with LazilyGenerated to avoid them appearing in your output unecessarily.
This transformation should generally always be used, and it must be used if you rely on the behavior described by LazilyGenerated.
This transformation must be run after TypeReductionTransformation or an equivalent. It does not handle type references which have not been reduced, so failing to do so will result in it removing all lazily-generated records.
