Struct Reconciler 

pub struct Reconciler { /* private fields */ }

Computes BG-23 and BG-22 from an invoice’s lines, allowances and charges.

Implementations

impl Reconciler

pub fn new() -> Self

Empty builder: no prepaid, rounding, or supplied exemptions.

pub fn exemption( self, category: impl Into<String>, text: Option<&str>, code: Option<&str>, ) -> Self

BT-120 / BT-121 for one category. Categories that forbid a reason drop it.

pub fn paid(self, amount: InvoiceAmount) -> Self

BT-113. Absent is not zero.

pub fn rounding(self, amount: InvoiceAmount) -> Self

BT-114. Malaysian 5-sen cash rounding belongs here, not as slack.

pub fn tax_total_accounting(self, amount: InvoiceAmount) -> Self

BT-111. Not derived.

pub fn compute(&self, inv: &Invoice) -> Result<Reconciled, ReconcileError>

Compute BG-23 and BG-22 without writing them back.

pub fn apply(&self, inv: &mut Invoice) -> Result<(), ReconcileError>

Write BG-23 and BG-22. Invoice is unchanged on error. Existing exemption reasons on matching groups are kept unless this reconciler supplied a replacement.
