// This header file defines an internal class that encapsulates internal message
// metadata (Unknown-field set, Arena pointer, ...) and allows its
// representation to be made more space-efficient via various optimizations.
//
// Note that this is distinct from google::protobuf::Metadata, which encapsulates
// Descriptor and Reflection pointers.
