Digital Twins represent a powerful paradigm for modelling complex IoT systems, yet practical implementations often fall short of theoretical promises. This talk cuts through the hype by demonstrating a robust approach based on an Actor Model pattern implemented in Rust, bridging the gap between conceptual frameworks and pragmatic engineering. Concurrency fundamentals, message-driven design patterns, and real-world use cases illustrate how Rust’s safety and performance guarantees enable maintainable, production-ready Digital Twin solutions.
