Converting the result List[MAp[String,Any]] into scala.Option[com.google.protobuf.struct.Struct]

[Sumiya92]

Hi Team,

i have proto file

message IOTDecodeRequest {
string id = 1;
string device_id = 2;
string device_parser_id = 3;
bytes raw_data = 4;
}

message IOTDecodeResult {
google.protobuf.Struct decoded = 1;
}

message IOTDecodeResponse {
int32 status = 1;
string id = 2;
IOTDecodeResult result = 3;
IOTDecodeError error = 4;
}

message IOTDecodeError {
int32 code = 1;
string message = 2;
string details = 3;
}

message IOTDecodeRequests {
repeated IOTDecodeRequest requests = 1;
}

message IOTDecodeResponses {
repeated IOTDecodeResponse responses = 2;
}

service IoTDecoderService {
rpc Decode(IOTDecodeRequests) returns (IOTDecodeResponses);
}

Am trying to implement the serviceImpletation for the data using proto:

i have result of raw_data from IOTDecodeRequest as List[Map[String,Any]] i need to convert it and pass it IOTDecodeResult as google.protobuf.Struct decode
for example :
val rawdata : List[Map[String,Any]] = List(Map("deviceid" -> 860267 , "altitude " -> 0.062),Map("deviceid" -> 860268 , "altitude " -> 0.062))

Please suggest on how to convert it or is there any way to convert it

Hi @Sumiya92 , it should be fairly straightforward to write a function on your own that iterates over the input and returns a Struct. I encourage you to try writing it :)

Hi @thesamet ,i have written a function for iterating the input but my question was really to construct struct value in scala , am passing Map[string,Any] but the struct required Map[string,Value] , i could not find any examples. any suggestions would be helpful.

It is constructed like any ScalaPB message (it’s just a case class. The code here converts from JSON to struct and back, so may be useful for inspiration. https://github.com/scalapb/scalapb-json4s/blob/master/src/main/scala/scalapb/json4s/StructFormat.scala
