Enumeration Type Documentation

ChannelId

enum class net::ChannelId : uint8_t

strong

Per-channel reliability + ordering semantics.

Stage 3d-1 ships only the enum; each channel's actual behaviour arrives with the packet types that use it.

Enumerator
Unreliable	No reliability. Drop stale by sequence comparison. Used for: snapshots, inputs (with redundancy at app layer).
UnreliableSequenced	No retransmit, but receiver discards packets older than the newest sequence already seen. Future: VFX bursts.
ReliableOrdered	Retransmit until acked, in-order delivery. Future: match-state, kill events, score updates.
ReliableUnordered	Retransmit until acked, no ordering required. Future: RPC.
Count

PacketKind

enum class net::PacketKind : uint8_t

strong

Packet kind discriminator (PacketHeader::kind field).

Enumerator
Payload	Application data ride this — snapshots, inputs, events.
ConnectionRequest	Future: connection handshake, keep-alive, disconnect. Stage 3d-1 doesn't use these yet — connectionId is established over the existing TCP path until handshake-over-UDP lands.
ConnectionAccepted
Disconnect
KeepAlive

Variable Documentation

k_maxPacketBytes

int net::k_maxPacketBytes = 1200

inlineconstexpr

Maximum total UDP payload (header + data) in bytes.

1200 is the safe MTU floor for the public Internet. Routers can fragment or drop bigger datagrams. Stage 3d-4 adds application-layer fragmentation for messages that exceed this.

k_maxPayloadBytes

int net::k_maxPayloadBytes = k_maxPacketBytes - static_cast<int>(sizeof(PacketHeader))

inlineconstexpr

Maximum payload bytes a single (non-fragmented) datagram can carry.

k_protocolMagic

uint16_t net::k_protocolMagic = 0x3247

inlineconstexpr

Magic bytes identifying our protocol. ASCII "G2" little-endian.

k_protocolVersion

uint8_t net::k_protocolVersion = 1

inlineconstexpr

Wire-format version. Bump on any layout change.
