Compile-time validation of PacketHeader wire format size. More...

Detailed Description

Compile-time validation of PacketHeader wire format size.

MoldUDP64 request packet for gap recovery

Request packet sent from client to server to recover missed messages. The client specifies which session and which sequence range needs to be retransmitted. The server responds with the requested messages.

Wire format (20 bytes):

• Session (10 bytes): ASCII session identifier to recover from
• Sequence Number (8 bytes): First missing sequence number
• Message Count (2 bytes): Number of consecutive messages to recover

The server will respond with one or more packets containing the requested messages, starting from the specified sequence number.

Note

All multi-byte fields are in network byte order (big-endian)

Maximum recoverable range is limited by count field (65535 messages)
