Struct MessageChunk 

pub struct MessageChunk {
    pub envelope: Arc<Vec<OwnedSegment>>,
    pub unh: OwnedSegment,
    pub body: Vec<OwnedSegment>,
    pub unt: OwnedSegment,
}

A single EDIFACT message (UNH…UNT) with its interchange envelope.

Fields

envelope: Arc<Vec<OwnedSegment>>

Interchange envelope segments (UNA, UNB) — shared across all messages via Arc.

unh: OwnedSegment

The UNH segment itself.

body: Vec<OwnedSegment>

Segments between UNH and UNT (exclusive of both).

unt: OwnedSegment

The UNT segment itself.

Implementations

impl MessageChunk

pub fn all_segments(&self) -> Vec<OwnedSegment>

Reconstruct the full segment list for this message (envelope + UNH + body + UNT).

Note: only use this when the MIG schema includes envelope segments (UNA, UNB). For MIG schemas that start at UNH, use message_segments() instead.

pub fn message_segments(&self) -> Vec<OwnedSegment>

Message-only segments (UNH + body + UNT), excluding interchange envelope.

Use this for assembly when the MIG schema starts at UNH (most message types). UTILMD MIG schemas include UNA/UNB, so those still need all_segments().

pub fn segments_for_mig(&self, mig: &MigSchema) -> Vec<OwnedSegment>

Return the appropriate segments for assembly based on whether the MIG includes envelope segments (UNA/UNB) or starts at UNH.

Trait Implementations

impl Clone for MessageChunk

fn clone(&self) -> MessageChunk

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MessageChunk

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
