   There're 2 ways to create a `Message` with C++ client
   
   ```c++
       /**
        * Set content of the message. The message contents will be managed by the system.
        */
       MessageBuilder& setContent(const void* data, size_t size);
       MessageBuilder& setContent(const std::string& data);
   
       /**
        * Set content of the message to a buffer already allocated by the caller. No copies of
        * this buffer will be made. The caller is responsible to ensure the memory buffer is
        * valid until the message has been persisted (or an error is returned).
        */
       MessageBuilder& setAllocatedContent(void* data, size_t size);
   ```
   
   - data: the pointer to your struct
   - size: the struct's size
