Struct ProvisionGenerator 

pub struct ProvisionGenerator { /* private fields */ }

Generates provisions and contingencies data for a reporting entity.

Implementations

impl ProvisionGenerator

pub fn new(seed: u64) -> Self

Create a new generator with a deterministic seed.

pub fn generate( &mut self, entity_code: &str, currency: &str, revenue_proxy: Decimal, reporting_date: NaiveDate, period_label: &str, framework: &str, prior_opening: Option<Decimal>, ) -> ProvisionSnapshot

Generate provisions and contingencies for one entity.

Parameters

• entity_code: company / entity identifier
• currency: reporting currency code (e.g. "USD")
• revenue_proxy: approximate annual revenue used to size warranty provisions
• reporting_date: balance-sheet date (provisions dated to this period)
• period_label: label for the movement roll-forward (e.g. "FY2024")
• framework: "IFRS" or "US_GAAP"
• prior_opening: opening balance of the provision from the prior period’s closing balance. When Some, the unwinding-of-discount is computed as prior_opening × discount_rate × period_fraction (IAS 37.60 / ASC 420). When None (first period or no carry-forward data), unwinding defaults to zero.
