SoupBinPacketType

enum class itch::transport::SoupBinPacketType : char

strong

The SoupBinTCP packet types (the one-byte type that follows the 2-byte length prefix).

SoupBinTCP is the reliable, ordered TCP framing NASDAQ uses for the Glimpse snapshot service and for recovery/replay. Only the server-to-client subset is needed to consume a captured or replayed stream, but every defined type is listed for completeness.

Enumerator
debug	Free-form debug text (either direction).
login_accepted	Session id (10) + starting sequence number (20, ASCII).
login_rejected	Reject reason code (1).
sequenced_data	One sequenced application (ITCH) message.
server_heartbeat	Keep-alive from the server.
end_of_session	The server has finished the session.
login_request	Client login request.
unsequenced_data	One unsequenced application message.
client_heartbeat	Keep-alive from the client.
logout_request	Client logout request.
