Domain Iot

This maps IoT domain constraints directly to Rust implementation choices. You get rules like "networks fail constantly" translated into concrete patterns: local buffering with persistence, exponential backoff, MQTT QoS levels. It covers the full spectrum from Linux gateways running tokio and rumqttc to no_std MCU code with embassy. The trace-down structure is the real value here, connecting "need power efficiency" to specific crate choices and sleep patterns. Includes working MQTT client code and a comparison table showing when to use std versus no_std stacks. Best used alongside the embedded and concurrency skills when you're building anything that talks to sensors or actuators over unreliable networks.

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

Critical Constraints

Network Unreliability

RULE: Network can fail at any time
WHY: Wireless, remote locations
RUST: Local queue, retry with backoff

Power Management

RULE: Minimize power consumption
WHY: Battery life, energy costs
RUST: Sleep modes, efficient algorithms

Device Security

RULE: All communication encrypted
WHY: Physical access possible
RUST: TLS, signed messages

Trace Down ↓

From constraints to design (Layer 2):

"Need offline-first design"
    ↓ m12-lifecycle: Local buffer with persistence
    ↓ m13-domain-error: Retry with backoff
