Trait UpdateSet 

pub trait UpdateSet {
    type Key: Hash + PartialEq + Eq + Ord + Serialize + DeserializeOwned;
    type Value: PartialEq + Serialize + DeserializeOwned;

    // Required methods
    fn value(&self) -> Self::Value;
    fn key(&self) -> Self::Key;
    fn should_be_deleted(&self) -> bool;
}

Helper trait fro working with fields that have either 2 or 3 tuple elements (present in the Stream API ladder)
