Crate iot_core 

iot-core

Foundation crate for the iot-protocols SDK. Defines the data model that every protocol implementation in the workspace agrees on:

• thing — Eclipse-Ditto-style Thing / Feature / Value digital twin.
• path — PropertyPath, the protocol-agnostic address of a single value.
• binding — ProtocolBinding / ThingMapping, the bridge that maps a PropertyPath onto a Modbus register, an MQTT topic, a CoAP URI, or an OPC UA NodeId.
• error — the unified error::IotError every public API returns.
• client — the client::IotClient async trait every protocol crate implements alongside its native API.

Feature flags

Feature	Adds	Default
std	std::error::Error impls, hashing	✓
alloc	Thing, Vec, dynamic BTreeMap maps	✓
serde	serde::{Serialize,Deserialize} derives
validate	JSON-Schema validation of Thing

With only alloc (no std) every public type continues to work, which is the configuration MCU targets compile.

Modules

binding

Bridge from the protocol-agnostic crate::path::PropertyPath to the concrete address used on the wire.

client

The unified IotClient async trait — the entry point of the “thick-unification” layer over MQTT, Modbus, CoAP, and OPC UA.

error

Unified error type returned across the SDK.

path

Protocol-agnostic property addressing.

thing

Identifiers and aggregates for the Eclipse-Ditto-style Thing model.

value

Self-describing scalar / collection values used by the Thing model.
