How to use Blob?

[miladamery]

Hi. I'm developing a Rust application using stargate-grpc-rust to connect to astra db. When issuing query one of my result set columns is of blobl type in astradb. how can I transform my ResultSet into rust specific struct.
Here is my struct:

struct location {
  city: String,
  longitude: f32,
  latitude: f32,
  name: String,
  image: Blob <-- how to get this?
}
