Struct EnvelopeOptions 

pub struct EnvelopeOptions { /* private fields */ }

How Mapper::to_edifact_interchange_with builds the interchange envelope.

The default is to regenerate: emit a UNA service string advice and stamp the UNB date and time from the clock. That is right for a re-send, and it is what Mapper::to_edifact_interchange does.

It is wrong for a caller comparing a render against its input, because the two differences are not about the message (issue #161). Such a caller has the original — the forward direction hands it back as Interchangedaten — and can ask for it here.

let options = EnvelopeOptions::default()
    .emit_una(false)
    .datum_zeit_from(&interchange.interchangedaten);

What this cannot reproduce

Non-default delimiters. The whole render — envelope and body alike — uses EdifactDelimiters::default, so an input whose UNA declared other delimiters cannot be reproduced, and emit_una(true) always advertises the defaults. Suppressing the UNA is honest about that; claiming delimiters the body does not honour would not be.

Implementations

impl EnvelopeOptions

pub fn emit_una(self, emit: bool) -> Self

Whether to emit the UNA service string advice. Default true.

An input that carried no UNA gains one unless this is false.

pub fn datum_zeit( self, datum: impl Into<String>, zeit: impl Into<String>, ) -> Self

Interchange date (yymmdd) and time (hhmm) for UNB, instead of the clock.

Both go into the header verbatim. A value that is not the right number of digits is refused when the interchange is rendered — with MapperError::MalformedEnvelopeDateTime, not silently — because UNB is the segment whose defects surface at the receiving gateway rather than anywhere the sender looks.

pub fn datum_zeit_from(self, daten: &Interchangedaten) -> Self

Take the UNB date and time from the Interchangedaten the forward direction produced. Fields it does not carry are left to the clock.
