/// Used for hooking different message serialization API's into GRPC.
/// Each SerializationTraits<Message> implementation must provide the
/// following functions:
/// 1. static Status Serialize(const Message& msg,
/// ByteBuffer* buffer,
/// bool* own_buffer);
/// OR
/// static Status Serialize(const Message& msg,
/// grpc_byte_buffer** buffer,
/// bool* own_buffer);
/// The former is preferred; the latter is deprecated
///
/// 2. static Status Deserialize(ByteBuffer* buffer,
/// Message* msg);
/// OR
/// static Status Deserialize(grpc_byte_buffer* buffer,
/// Message* msg);
/// The former is preferred; the latter is deprecated
///
/// Serialize is required to convert message to a ByteBuffer, and
/// return that byte buffer through *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_receive_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.
