This is the Rust code if anyone experienced with that decides to pitch in:
```
/// Provide the schema of a table in the catalog. The name of the table must
/// be provided as the first element in `FlightDescriptor.path`.
async fn get_schema(
&self,
request: Request<FlightDescriptor>,
) -> Result<Response<SchemaResult>, Status> {
let flight_descriptor = request.into_inner();
let table_name =
self.get_table_name_from_flight_descriptor(&flight_descriptor)?;
let schema = self.get_table_schema_from_default_catalog(table_name)?;
let options = IpcWriteOptions::default();
let schema_as_ipc = SchemaAsIpc::new(&*schema, &options);
let serialized_schema = schema_as_ipc
.try_into()
.map_err(|error: Infallible| Status::internal(error.to_string()))?;
Ok(Response::new(serialized_schema))
}
```
