Issue with a simple GET command

[PaulDotSH]

Hi, the following coding snippet

  if let Ok(encoded) = redis::cmd("GET")
        .arg(&encoded_filter)
        .query_async::<_, Vec<u8>>(&mut conn)
        .await {}

ALWAYS returns Ok, even when the key is NOT present in redis, it just choses to return an empty vec. Why does this happen? How can I fix it?

Cast to Option<Vec<u8>> instead of Vec. A missing key isn't an error.
