You can change your server code to
```
async fn get_schema(
&self,
_request: Request<FlightDescriptor>,
) -> Result<Response<SchemaResult>, Status> {
let tid = Field::new("tid", DataType::Int32, false);
let timestamp = Field::new("timestamp",
DataType::Timestamp(TimeUnit::Millisecond, None), false);
let value = Field::new("value", DataType::Float32, false);
let schema = Schema::new(vec![tid, timestamp, value]);
let options = IpcWriteOptions::default();
let schema_as_ipc = SchemaAsIpc::new(&schema, &options);
// convert the schema as the ipc message
let ipc_message : IpcMessage =
IpcMessage::try_from(schema_as_ipc).unwrap();
// wrap the `SchemaResult` using the ipc message bytes
let schema_result: SchemaResult = SchemaResult {
schema: ipc_message.0,
}
Ok(Response::new(schema_result))
}
```
