Struct SamplingPlanGenerator 

pub struct SamplingPlanGenerator { /* private fields */ }

Generator for ISA 530 sampling plans and sampled items.

Implementations

impl SamplingPlanGenerator

pub fn new(seed: u64) -> Self

Create a new generator with default configuration.

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

Create a new generator with custom configuration.

pub fn generate_for_cras( &mut self, cras: &[CombinedRiskAssessment], tolerable_error: Option<Decimal>, ) -> (Vec<SamplingPlan>, Vec<SampledItem>)

Generate sampling plans and sampled items for all CRAs at Moderate or higher.

Arguments

• cras — All combined risk assessments for one or more entities.
• tolerable_error — Performance materiality / tolerable error for the entity. When None, a synthetic TE of 5% of the base population value is used.

Returns (plans, sampled_items) — the plans and the flat list of all sampled items.

pub fn generate_for_cras_with_population( &mut self, cras: &[CombinedRiskAssessment], tolerable_error: Option<Decimal>, journal_entries: &[JournalEntry], ) -> (Vec<SamplingPlan>, Vec<SampledItem>)

Generate sampling plans using real journal entry population data.

Key items are actual JE lines with amount > tolerable_error. Representative items are sampled from the remaining JE population. Falls back to synthetic generation for CRAs with no matching JE lines.
