just suply in some case like this: I have a message, maybe use json or protobuf or anything else protocol. We just describe its protocol with protobuf, but encoding or decoding will be transparent for developer. Developer just tell us its protocol and codec type, then we generate coder file.
exampler:
type Codec interface {
Marshal(msg interface{}) ([]byte, error)
Unmarshal (data []byte, msg interface{}) (error)
}

User.proto
message User {
required int64 id = 1;
required string name = 2
required int32 age = 3;
optional Occupation occ = 4;
repeated Occupation occs = 5;
}
message Occupation {
required int64 id = 1;
required string industry = 2;
}

user := &User{}
user.Unmarshal & user.Marshal, don't case json or protobuf.
