TwinState 类
定义
Representation of a single Twin.
The TwinState can contain one TwinCollection of Tags, and one TwinCollection of properties.desired.
Each entity in the collections can contain a associated TwinMetadata.
These metadata are provided by the Service and contains information about the last updated date time, and version.
For instance, the following is a valid TwinState, represented as
initialTwin
