Build a Rust edge device by using Tokio for async execution, tokio-modbus for sensor communication, and rumqttc for MQTT messaging. This pattern enables concurrent data polling and publishing for industrial IoT workloads.

Structure an async Rust application using a Tokio runtime with Serde for data serialization and thiserror for error handling. This combination ensures maintainable, concurrent execution for industrial IoT communication protocols.

Yes, the Rust systems pattern supports exposing an HTTP API using Axum. This allows the edge service to handle industrial Modbus and MQTT data while simultaneously providing a health check or service interaction endpoint.

Tokio handles concurrent Modbus polling and MQTT publishing by providing an asynchronous runtime that executes multiple I/O tasks without blocking. This allows Rust edge computing systems to simultaneously read sensors and publish messages.

Use thiserror in a Rust async edge computing system when you need structured, custom error types across application layers. It integrates with Tokio and Serde to ensure consistent error propagation during Modbus and MQTT operations.
