DeepMarshalJSON marshals msg to w as JSON, but instead of marshaling bytes fields which contain nested marshaled messages as base64 (like the standard proto encoding), these nested messages are remarshaled as the JSON representation of those messages.

DeepUnmarshalJSON takes JSON output as generated by DeepMarshalJSON and decodes it into msg This includes re-marshaling the expanded nested elements to binary form.

MostlyDeterministicMarshal is _NOT_ the function you are looking for.

DecoratedProto should be implemented by the dynamic wrappers applied by the Dynamic*FieldProto interfaces This is necessary for the proto system to unmarshal, because it discovers proto message type by reflection (Rather than by interface definition as it probably should ( https://github.com/golang/protobuf/issues/291 ).

DynamicFieldProto should be implemented by protos which have nested fields whose attributes (such as their opaque types) cannot be determined until runtime.

DynamicMapFieldProto should be implemented by protos which have maps to messages whose attributes (such as their opaque types) cannot be determined until runtime.

DynamicSliceFieldProto should be implemented by protos which have slices of messages whose attributes (such as their opaque types) cannot be determined until runtime.

StaticallyOpaqueFieldProto should be implemented by protos which have bytes fields which are the marshaled value of a fixed type.

StaticallyOpaqueMapFieldProto should be implemented by protos which have maps to bytes fields which are the marshaled value of a fixed type.

StaticallyOpaqueSliceFieldProto should be implemented by protos which have maps to bytes fields which are the marshaled value of a fixed type.

VariablyOpaqueFieldProto should be implemented by protos which have bytes fields which are the marshaled value depends upon the other contents of the proto.

VariablyOpaqueMapFieldProto should be implemented by protos which have maps to bytes fields which are the marshaled value of a a message type determined by the other contents of the proto.

VariablyOpaqueSliceFieldProto should be implemented by protos which have maps to bytes fields which are the marshaled value of a a message type determined by the other contents of the proto.
