echonet (uecho-rs)

The uecho-rs is a portable and cross-platform development framework for creating controller applications and devices of ECHONET-Lite for Rust developers. ECHONET-Lite is an open standard specification for IoT devices in Japan, it specifies more than 100 IoT devices such as crime prevention sensors, air conditioners and refrigerators.

What is uEcho ?

To implement IoT controllers or devices of ECHONET-Lite, the developer had to understand and implement the communication middleware specification such as the message format and base sequences.

The uecho-rs provides the following major components to control ECHONET-Lite devices and create the standard specification devices.

• ECHONET-Lite controller to find and control ECHONET-Lite nodes.
• ECHONET-Lite device framework to implement any standard ECHONET-Lite devices.
• Decoder and Encoder for ECHONET-Lite messaging packet.
• Standard device database based on Machine Readable Appendix and Manufacturer code List provided by the ECHONET Consortium.

The uecho-rs handles all ECHONET-Lite requests such as read, write and notification requests automatically. Therefore, Rust developers can implement the standard device and controller applications using the uecho-rs easily by simply implementing the request message validators.

Modules

log

Logger function module.

protocol

messaging packet encoder and decoder module.

Messaging transport manager module (Internal).

util

Utility function module.

Structs

Controller

Controller represents an ECHONET-Lite controller node to communicate other ECHONET-Lite nodes.

Device

Device represents an ECHONET-Lite device node. The device is created with a standard device object code, and the object is automatically added the standard properties which are specified in APPENDIX Detailed Requirements for ECHONET Device Objects by the ECHONET Consortium.

Manufacture

Manufacture represents a manufacturer name and code registerd by the ECHONET CONSORTIUM.

Node

Node represents an ECHONET-Lite node which contains ECHONET-Lite objects such the profiles and the devices.

Object

Each ECHONET-Lite node has objects. Object represents an ECHONET-Lite Object in an ECHONET-Lite node.

Property

Each ECHONET-Lite object has properties. Property represents an ECHONET-Lite property in an ECHONET-Lite object.

PropertyEnum

PropertyEnum represents an ECHONET-Lite property enumerated data.

RemoteNode

RemoteNode represents an ECHONET-Lite node discovered by Controller. The remote node has the standard objects and properties defined by the ECHONET CONSORTIUM.

StandardDatabase

StandardDatabase provides a standard database for ECHONET-Lite device objects and manufactures. This standard database was generated by importing Machine Readable Appendix and Manufacturer code List provided by the ECHONET Consortium.

Enums

PropertyRule

PropertyRule represents an ECHONET-Lite property access rule.

Traits

RequestHandler

RequestHandler defines a request message handler interface.

Type Aliases

ManufactureCode

ManufactureCode represents a manufacturer code registerd by the ECHONET CONSORTIUM.

ObjectCode

ObjectCode represents an ECHONET-Lite object code.

RequestHandlerObject

RequestHandlerObject represents a request message handler object.
