Crate core_invoice 

Semantic model for the core electronic invoice: EN 16931 and Peppol PINT.

Tax is VAT, GST, SST, or consumption — not VAT only. No I/O, no tax-authority APIs, no accounting UI.

Modules

amount

InvoiceAmount (≤2 fraction digits, refuse excess) and UnitPriceAmount (uncapped).

arith

Rounding and slack used by VAT/GST/SST derivation.

attachment

Binary Attachment: bytes, MIME, and filename (BT-125).

bt

Finding locations: BtId, Group, Path. Repeating-group index is 0-based.

category

Nine UNCL 5305 VAT category families plus PINT-MY aligned tables.

code

Verbatim Code. List membership is a rule (BR-CL-*), not a constructor.

codes

Code lists generated from refers/ genericode (code points only; EUPL XML stays out of git).

date

Calendar Date: YYYY-MM-DD, no time, no timezone. Invalid input fails closed.

error

Construction errors for amounts, dates, and attachments.

identifier

Identifier (value + optional scheme) and DocumentReference (content only).

invoice

Semantic invoice: parties, lines, totals, and Table 2 groups.

kind

Syntax root DocumentKind. Not derived from BT-3.

numeric

Quantity (signed, not money) and Percentage (per cent, not a fraction).

payment

Exclusive payment means: BG-17 credit transfer, BG-18 card, or BG-19 direct debit.

peppol

Peppol BIS Billing 3.0 extra_rules. Not CORE, not inherited by PINT.

profile

Usage specification (BT-24). Profiles are siblings, not a ladder.

proof

Proof that an invoice passed a named profile. Formats stamp BT-24 from this.

reconcile

Derive BG-23 and BG-22 from lines, document allowances and charges.

report

Validation findings. Severity::Fatal fails Report::ok; Severity::Warning does not.

rules

Rule registry. crate::validate() and explain share one table.

tax

Tax system and category. SST is in-memory; wire_scheme never emits TaxScheme SST.

validate

Semantic checks on the in-memory invoice.
