public static @interface CustomType.Constructor
```
Annotation used by a Pulumi Cloud Provider Package to marks the constructor for a complex property type so that it can be instantiated by the Pulumi runtime.
WARNING: nested classes will have a reference to the parent class as the as the first parameter of the constructor (arg0) and this type also needs to be deserializable or the class needs to be made static. This is unlikely scenario, but theoretically possible. The invisible fist argument needs also to be named in the annotation value.
The constructor should take parameters annotated with CustomType.Parameter that map to the resultant @see Struct returned by the engine.
