public record ChatMessageC2SPacket(String chatMessage, Instant timestamp, long salt, @Nullable MessageSignatureData signature, LastSeenMessageList.Acknowledgment acknowledgment) extends Record implements Packet<ServerPlayPacketListener>
A packet used to send a chat message to the server.

This truncates the message to at most 256 characters before sending to the server on the client. If the server receives the message longer than 256 characters, it will reject the message and disconnect the client.

If the message contains an invalid character (see SharedConstants.isValidChar(char)) or if the server receives the messages in improper order. the server will reject the message and disconnect the client.

Messages that took more than SignedMessage.SERVERBOUND_TIME_TO_LIVE to reach the server are considered expired and log warnings on the server. If the message takes more than SignedMessage.CLIENTBOUND_TIME_TO_LIVE to reach the clients (including the time it took to reach the server), the message is not considered secure anymore by the clients, and may be discarded depending on the clients' options.
