Struct SegmentStructure 

pub struct SegmentStructure { /* private fields */ }

Maps segment tags to their expected element count from the MIG schema.

Element count = data_elements.len() + composites.len() for each segment. This matches the EDIFACT convention where each data element or composite occupies one element position separated by +.

Implementations

impl SegmentStructure

pub fn from_mig(mig: &MigSchema) -> Self

Build from a MIG schema by walking all segments (top-level and within groups).

First occurrence of a segment tag wins — the same tag always has the same element structure in EDIFACT.

pub fn element_count(&self, tag: &str) -> Option<usize>

Look up the expected element count for a segment tag.
