+/// Defines how to serialize and deserialize some type.
+///
+/// Used for hooking different message serialization API's into GRPC.
+/// Each SerializationTraits implementation must provide the following
+/// functions:
+///   static Status Serialize(const Message& msg,
+///                           grpc_byte_buffer** buffer,
+//                            bool* own_buffer);
+///   static Status Deserialize(grpc_byte_buffer* buffer,
+///                             Message* msg,
+///                             int max_message_size);
+///
+/// Serialize is required to convert message to a grpc_byte_buffer, and
+/// to store a pointer to that byte buffer at *buffer. *own_buffer should
+/// be set to true if the caller owns said byte buffer, or false if
+/// ownership is retained elsewhere.
+///
+/// Deserialize is required to convert buffer into the message stored at
+/// msg. max_message_size is passed in as a bound on the maximum number of
+/// message bytes Deserialize should accept.
+///
+/// Both functions return a Status, allowing them to explain what went
+/// wrong if required.
