Struct Disassembler 

pub struct Disassembler<'a> { /* private fields */ }

MIG-guided disassembler — walks the MIG tree to emit segments in correct order.

Implementations

impl<'a> Disassembler<'a>

pub fn new(mig: &'a MigSchema) -> Self

pub fn disassemble(&self, tree: &AssembledTree) -> Vec<DisassembledSegment>

Disassemble a tree into ordered segments following MIG sequence.

Emits segments in correct EDIFACT order:

1. Pre-group top-level segments (e.g., UNB, UNH, BGM, DTM)
2. Groups (recursively, in MIG order)
3. Post-group top-level segments (e.g., UNT, UNZ)

Uses MIG-guided ordering: walks the MIG schema tree and looks up matching data in the assembled tree. This handles both assembler output (already in MIG order) and reverse-mapped trees (may be in arbitrary order).
