AHB field definition for validation.

Represents a single field in an AHB rule table with its status and allowed codes for a specific Pruefidentifikator.

Fields

segment_path: String

Segment path (e.g., “SG2/NAD/C082/3039”).

name: String

Human-readable field name (e.g., “MP-ID des MSB”).

ahb_status: String

AHB status (e.g., “Muss [182] ∧ [152]”, “X”, “Kann”).

codes: Vec<AhbCodeRule>

Allowed code values with their AHB status.

parent_group_ahb_status: Option<String>

AHB status of the innermost parent group (e.g., “Kann”, “Muss”, “Soll [46]”).

When the parent group is optional (“Kann”) and its qualifier variant is absent from the message, mandatory checks for child fields are skipped.

segment_ahb_status: Option<String>

AHB status of the containing segment (e.g., “Kann”, “Muss”, “Muss [10]”).

When the containing segment is optional (“Kann”) and absent from the instance, AHB001 missing-field errors on its sub-fields are suppressed: “X” on a Kann segment’s sub-element means “required IF segment present”.

element_index: Option<usize>

Element index within the segment (0-based). Used to locate the correct element when checking presence and code values. None defaults to 0.

component_index: Option<usize>

Component sub-index within a composite element (0-based). Used to locate the correct component. None defaults to 0.

mig_number: Option<String>

MIG Number attribute of the parent segment. Links this AHB field to the corresponding AssembledSegment::mig_number for tree-based joining.

format: Option<String>

The MIG data format, e.g. "an..512", "n13". None when unknown.

group_ahb_status: Option<String>

The innermost enclosing group’s own AHB status, as the AHB writes it (Muss [81] on 55035’s SG10 Zugeordnete Definition), where parent_group_ahb_status ANDs every conditional ancestor’s condition under Muss (Muss ([166] ∧ [205]) ∧ ([81])). Whether an absent child group is required is its own status, judged in its present parent. None for workflows built before it existed.
