Capn proto is like a RAM format that can be directly serialized. This is a serialization format that can be directly worked with. They both allow skipping deserialization, but that's not the main draw of this approach. The ability to design data representation around expected access patterns can make traversal faster and data more compact even if you don't plan to ever "serialize" it.
