Architecture & Performance Blueprint — opcua2mqtt
Engineered in pure Rust with strict adherence to industrial deterministic latency and air-gapped IEC 62443 cybersecurity requirements.
Key Architectural Invariants
- Zero Garbage Collection: Predictable p99 latency without runtime stop-the-world pauses.
- Air-Gapped MQTT & OPC UA Operation: 100% offline Ed25519 license verification and zero outbound internet dependencies.
- Embedded WAL: Local non-volatile storage buffer decoupling PLC collection from MQTT network connectivity.
