Struct ExpenseReportGenerator 

pub struct ExpenseReportGenerator { /* private fields */ }

Generates ExpenseReport records for employees over a period.

Implementations

impl ExpenseReportGenerator

pub fn new(seed: u64) -> Self

Create a new expense report generator with default configuration.

pub fn with_config(seed: u64, config: ExpenseConfig) -> Self

Create an expense report generator with custom configuration.

pub fn set_temporal_context(&mut self, ctx: Arc<TemporalContext>)

Set the shared TemporalContext so submission / approval / paid / line-item dates snap to the next business day.

pub fn with_temporal_context(self, ctx: Arc<TemporalContext>) -> Self

Builder variant of Self::set_temporal_context.

pub fn set_country_pack(&mut self, pack: CountryPack)

Set the country pack for locale-aware generation.

When set, the generator can use locale-specific currencies and business rules from the country pack. Currently the pack is stored for future expansion; existing behaviour is unchanged when no pack is provided.

pub fn with_pools( self, employee_ids: Vec<String>, cost_center_ids: Vec<String>, ) -> Self

Set ID pools for cross-reference coherence.

When pools are non-empty, the generator selects approved_by from employee_ids and cost_center from cost_center_ids instead of fabricating placeholder IDs.

pub fn with_employee_names(self, names: HashMap<String, String>) -> Self

Set the employee name mapping for denormalization (DS-011).

Maps employee IDs to their display names so that generated expense reports include the employee name for graph export convenience.

pub fn generate_from_config( &mut self, employee_ids: &[String], period_start: NaiveDate, period_end: NaiveDate, ) -> Vec<ExpenseReport>

Generate expense reports using the stored config and country pack.

Uses self.config for submission rate and policy thresholds, and self.country_pack for locale-specific currency.

pub fn generate( &mut self, employee_ids: &[String], period_start: NaiveDate, period_end: NaiveDate, config: &ExpenseConfig, ) -> Vec<ExpenseReport>

Generate expense reports for employees over the given period.

Only config.submission_rate fraction of employees submit reports each month within the period.

Arguments

• employee_ids - Slice of employee identifiers
• period_start - Start of the period (inclusive)
• period_end - End of the period (inclusive)
• config - Expense management configuration (overrides stored config)

pub fn generate_with_currency( &mut self, employee_ids: &[String], period_start: NaiveDate, period_end: NaiveDate, config: &ExpenseConfig, currency: &str, ) -> Vec<ExpenseReport>

Generate expense reports with a specific company currency.
