Define Message Structure for Network Communication #15
Description
This issue aims to define the message structure for network communication, drawing inspiration from the existing local_chat/message.rs implementation. The new structure will extend the current design to include network-specific fields, such as headers for metadata, timestamps, or unique identifiers for message tracking. This enhancement will ensure that messages are well-defined and easily transferable over the network, facilitating efficient communication between clients and servers while maintaining clarity and consistency in message handling.
