Struct FraudPatternMatch 

pub struct FraudPatternMatch { /* private fields */ }

Fraud pattern matching kernel.

Combines multiple fraud detection techniques:

• Aho-Corasick for string pattern matching
• Rapid split detection for structuring
• Cycle detection for circular flows
• Statistical anomaly detection

Implementations

impl FraudPatternMatch

pub fn new() -> Self

Create a new fraud pattern match kernel.

pub fn compute( transaction: &BankTransaction, history: &[BankTransaction], patterns: &[FraudPattern], profile: Option<&AccountProfile>, ) -> FraudDetectionResult

Detect fraud patterns in a transaction.

Arguments

• transaction - Transaction to analyze
• history - Recent transaction history for the account
• patterns - Fraud patterns to check
• profile - Account profile for baseline comparison

pub fn compute_batch( transactions: &[BankTransaction], history_map: &HashMap<u64, Vec<BankTransaction>>, patterns: &[FraudPattern], profiles: &HashMap<u64, AccountProfile>, ) -> Vec<FraudDetectionResult>

Batch analyze multiple transactions.

pub fn standard_patterns() -> Vec<FraudPattern>

Create standard fraud patterns.
