Fields

new_vendor_threshold_days: u32

Threshold for “new” vendor in days.

new_vendor_error_multiplier: f64

Error rate multiplier for new vendors.

new_vendor_error_types: Vec<AnomalyType>

Anomaly types more common with new vendors.

strategic_vendor_spend_threshold: Decimal

Threshold for “strategic” vendor by total spend.

strategic_vendor_types: Vec<AnomalyType>

Anomaly types for strategic vendors (typically fraud).

international_error_types: Vec<AnomalyType>

International vendor FX/tax error types.

dormant_vendor_threshold_days: u32

Dormant vendor threshold in days.

dormant_reactivation_multiplier: f64

Error multiplier for dormant vendor reactivation.

Implementations

impl VendorAnomalyRules

pub fn is_new_vendor( &self, creation_date: NaiveDate, current_date: NaiveDate, ) -> bool

Checks if a vendor is considered “new”.

pub fn is_dormant_vendor( &self, last_activity: NaiveDate, current_date: NaiveDate, ) -> bool

Checks if a vendor is “dormant” (no activity for threshold period).

pub fn is_strategic_vendor(&self, total_spend: Decimal) -> bool

Checks if a vendor is “strategic” based on total spend.

pub fn get_multiplier(&self, context: &VendorContext) -> f64

Gets the error rate multiplier for a vendor.

pub fn get_applicable_types(&self, context: &VendorContext) -> Vec<AnomalyType>

Gets applicable anomaly types for a vendor context.
