pub struct FunctionalCurrencyTranslator;
Expand description

Generator for IAS 21 functional-currency translations.

Implementations§

Source§

impl FunctionalCurrencyTranslator

Source

pub fn translate( entity_code: &str, functional_currency: &str, presentation_currency: &str, period_label: &str, period_end: NaiveDate, revenue_proxy: Decimal, rate_table: &FxRateTable, ) -> CurrencyTranslationResult

Translate a single entity for one reporting period.

§Parameters
  • entity_code — company / entity identifier
  • functional_currency — entity’s functional currency (ISO 4217)
  • presentation_currency — group presentation currency (ISO 4217)
  • period_label — human-readable period, e.g. “2024-12”
  • period_end — last day of the period
  • revenue_proxy — scale for synthetic amounts (functional currency)
  • rate_table — pre-populated FxRateTable

Returns None when functional == presentation (no translation needed; a zero-CTA result is still constructed for completeness).
