domain-iot
Design patterns and constraints for building reliable, power-efficient IoT applications in Rust.
- Covers six critical domains: network unreliability, power constraints, resource limits, security, reliability, and over-the-air updates with specific Rust implementation strategies
- Provides MQTT client patterns using rumqttc for pub/sub messaging with QoS levels, local buffering, and retry logic with exponential backoff
- Distinguishes between Linux gateway stacks (tokio + std) and MCU device stacks (embassy + no_std) with recommended crates for each environment
- Includes design patterns for offline-first operation, edge computing, signed firmware updates with rollback, and battery-aware sleep modes
IoT Domain
Layer 3: Domain Constraints
Domain Constraints → Design Implications
| Domain Rule | Design Constraint | Rust Implication |
|---|---|---|
| Unreliable network | Offline-first | Local buffering |
| Power constraints | Efficient code | Sleep modes, minimal alloc |
| Resource limits | Small footprint | no_std where needed |
| Security | Encrypted comms | TLS, signed firmware |
| Reliability | Self-recovery | Watchdog, error handling |
| OTA updates | Safe upgrades | Rollback capability |
