	Sequence number type (64-bit unsigned for MoldUDP64).
using	MsgType = const MessageBlock*
	Message type (pointer to MessageBlock).
using	PacketType = UDPPacket
	Packet type for parsing incoming datagrams.

Static Public Member Functions
static MsgType	null_message ()
	Get a null message sentinel value.

Static Public Attributes
static constexpr unsigned	ChunkSize = 4096
	Memory pool chunk size in bytes (4KB chunks).
static constexpr unsigned	NumChunks = 10
	Number of memory pool chunks (40KB total).

Member Function Documentation

null_message()

MsgType b2bits::nasdaq::moldudp64::SequencerImpl::Traits::null_message ( )

inlinestatic

Get a null message sentinel value.

Returns a null pointer to represent "no message" in the sequencer. Used for gap placeholders and uninitialized slots.

Returns

nullptr as the null message indicator
