Crate datasynth_core 

synth-core

Core domain models, traits, and distributions for synthetic accounting data generation.

This crate provides the foundational types used throughout the synthetic data factory:

• Journal Entry models (header and line items)
• Chart of Accounts structures
• SAP HANA ACDOCA/BSEG compatible event log formats
• Generator and Sink traits for extensibility
• Statistical distribution samplers based on empirical research
• Templates for realistic data generation (names, descriptions, references)
• Resource management (memory, disk, CPU) with graceful degradation
• Streaming infrastructure for real-time data generation
