+resource-restricted systems, like Android. It is very resource-friendly in both
+the amount of code and the runtime overhead. Here is an overview of JavaNano

- No descriptors or message builders.
- All messages are mutable; fields are public Java fields.
- For optional fields only, encapsulation behind setter/getter/hazzer/
clearer functions is opt-in, which provide proper 'has' state support.
-- If not opted in, has state is not available. Serialization outputs
