Does the library identify when it ends and starts the Struct in the buffer?

Hi Renzo The library provides ResponseContainer receiveMessageUntil(char delimiter = '\0'); which allows sending a string with a "\0" delimiter at the end. With this, the Receiver, when reading the buffer, identifies when a message starts and ends. Does the same happen when sending a Struct? I was analyzing the library code (I'm a beginner), but I didn't identify which strategy is used to identify the beginning and end of a Struct in the buffer. How does ResponseStructContainer receiveMessage(const uint8_t size); know/identify when a Struct ends and starts another Struct in the buffer? If there is no such identification, if the developer makes a mistake in the buffer reading strategy, will this cause a memory leak?
