Struct Objective 

pub struct Objective {
    pub column: String,
    pub goal: Goal,
    pub aggregate: Aggregate,
}

Output a search scores candidates by, and the direction it prefers.

Fields

column: String

Output column, a reducer column such as Infected:max.

goal: Goal

Direction the search prefers.

aggregate: Aggregate

Rule that folds the replicates of a candidate into one value.
