Struct StructuredFieldMapping 

pub struct StructuredFieldMapping {
    pub target: String,
    pub transform: Option<String>,
    pub when: Option<String>,
    pub default: Option<String>,
    pub enum_map: Option<BTreeMap<String, String>>,

}

A structured field mapping with optional transform and condition.

Fields

target: String

transform: Option<String>

when: Option<String>

default: Option<String>

enum_map: Option<BTreeMap<String, String>>

Bidirectional enum translation map (EDIFACT value → BO4E value). Forward: looks up extracted EDIFACT value to produce BO4E value. Reverse: reverse-looks up BO4E value to produce EDIFACT value. Uses BTreeMap for deterministic reverse lookup (first key alphabetically wins).

when_filled: Option<Vec<String>>

Conditional injection: only inject the default on reverse when ANY of these target field names has a value in the BO4E JSON (checked in both core and companion objects). Used for transport metadata (qualifiers, codelist codes) that should only appear when associated domain data exists.

also_target: Option<String>

Second target for dual decomposition: one EDIFACT value → two companion fields. Used when a code encodes two concepts (e.g., NAD qualifier = partnerrolle + datenqualitaet). Forward: map raw value via also_enum_map, store as also_target. Reverse: joint lookup — find code where both enum_map and also_enum_map match.

also_enum_map: Option<BTreeMap<String, String>>

Enum map for the also_target field. Same code keys as enum_map.
