Parsed UNB interchange envelope header fields.

All fields come from the UNB segment of the EDIFACT interchange. Use these for routing, acknowledgement generation, and audit logging.

Fields

sender_id: Box<str>

Sender identification (UNB S002, DE 0004 — e.g. a 13-digit GLN).

sender_qualifier: Box<str>

Sender qualifier (UNB S002, DE 0007 — e.g. "14" for GS1 GLN).

receiver_id: Box<str>

Recipient identification (UNB S003, DE 0010 — e.g. a 13-digit GLN).

receiver_qualifier: Box<str>

Recipient qualifier (UNB S003, DE 0007).

transmission_datetime: Option<OffsetDateTime>

Preparation date+time from UNB S004 (DE 0017 + DE 0019).

None when the UNB date/time fields are absent or malformed.

control_ref: Box<str>

Interchange control reference (UNB DE 0020).

syntax_id: Box<str>

EDIFACT syntax identifier from UNB S001 (DE 0001 — e.g. "UNOC").

syntax_version: u8

EDIFACT syntax version number from UNB S001 (DE 0002 — e.g. 3).

test_indicator: bool

Test indicator from UNB DE 0035.

true when DE 0035 is "1". Per Allgemeine Festlegungen V6.1d §3, interchanges with the test flag must not be processed as production messages. Reject at the ingest boundary and record a dead-letter entry.
