+ * NOTE: This is React Native specific export type.
+ *
+ * RCTExport is an interface type that allows native code generation for React
+ * Native native modules. It exists as a hint to the codegen tool that any
+ * interface that extends it needs to be codegen'ed. Example usage:
+ *
+ *   export interface RCTFoobar extends RCTExport<void> {}
+ *
+ * Native definition for RCTFoobar will then be generated.
+ *
+ * The type param T is a placeholder for future codegen hinting, like versioning
+ * information, native base classes, etc. For now, simply use `void` type as
+ * there's nothing to give hint about.
