Member Data Documentation

choice

PduChoice libe3::Pdu::choice

Definition at line 347 of file types.hpp.

enqueue_seq

uint64_t libe3::Pdu::enqueue_seq {0}

Set by queue_outbound; keys the [latrec] L-stage records.

Definition at line 349 of file types.hpp.

message_id

uint32_t libe3::Pdu::message_id {0}

Unique message identifier.

Definition at line 348 of file types.hpp.

timestamp

uint64_t libe3::Pdu::timestamp {0}

Producer timestamp, in nanoseconds since the Unix epoch.

Stamped from the realtime clock (see now_realtime_ns) when the PDU is constructed, so a caller gets one for free. Zero means "no producer reference": every encoding transmits it as an absent field and decodes an absent field back to zero, so the clock read is opt-out and a PDU without a timestamp is a normal message rather than a malformed one.

Warning

Realtime, not monotonic. Never subtract it from a monotonic reading.
