|
/// 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_receive_message_size is passed in as a bound on the maximum |
|
/// number of message bytes Deserialize should accept. |
