Crate mig_bo4e 

Declarative TOML-based MIG-tree <-> BO4E mapping engine.

Architecture

• TOML mapping files define simple 1:1 field mappings
• Complex handlers are Rust functions for non-trivial logic
• MappingEngine loads all definitions and provides bidirectional conversion

Usage

let engine = MappingEngine::load("mappings/FV2504/UTILMD_Strom/pid_55001")?;
let def = engine.definition_for_entity("Marktlokation").unwrap();
let bo4e = engine.map_forward(&tree, def, 0);
let instance = engine.map_reverse(&bo4e, def);

Modules

code_lookup

Code enrichment lookup — maps EDIFACT companion field codes to human-readable meanings.

definition

TOML mapping definition types.

engine

Mapping engine — loads TOML definitions and provides bidirectional conversion.

error

error_mapping

Maps EDIFACT validation paths to BO4E field paths.

handlers

Complex mapping handler registry.

model

Output model types for the MIG-driven mapping pipeline.

path_resolver

Resolves EDIFACT ID paths to numeric element indices (and vice versa).

pid_requirements

PID field requirements — built from PID schema JSON + TOML mappings.

pid_schema_index

Lightweight PID schema index for checking which groups exist in a PID.

pid_validation

PID validation errors — typed, LLM-consumable error reports.

segment_structure

MIG-aware segment structure lookup.

Structs

Interchange

A complete EDIFACT interchange. M = message stammdaten, T = transaction stammdaten.

Interchangedaten

EDIFACT interchange envelope metadata (UNB/UNZ).

Nachricht

A single EDIFACT message within an interchange.

Nachrichtendaten

EDIFACT message metadata (UNH/UNT).

Type Aliases

DynamicInterchange

Dynamic variant for untyped usage.

DynamicNachricht

Dynamic variant for untyped message usage.
