ocpp/custom_data

The OCPP 2.x CustomData vendor-extension type.

In the schemas, CustomDataType is an open object: it carries a required vendorId plus arbitrary additional vendor-specific properties (it is the one type that does NOT get additionalProperties: false). For now only vendorId is modelled; passthrough of arbitrary extra properties is a planned enhancement (it needs a transport-neutral representation of an open value).

pub type CustomData {
  CustomData(vendor_id: String)
}
