pub struct IndexAssignment<VoterIndex, TargetIndex, P: PerThing> {
    pub who: VoterIndex,
    pub distribution: Vec<(TargetIndex, P)>,
}
Expand description

The IndexAssignment type is an intermediate between the assignments list (&[Assignment<T>]) and SolutionOf<T>.

The voter and target identifiers have already been replaced with appropriate indices, making it fast to repeatedly encode into a SolutionOf<T>. This property turns out to be important when trimming for solution length.

Fields§

§who: VoterIndex

Index of the voter among the voters list.

§distribution: Vec<(TargetIndex, P)>

The distribution of the voter’s stake among winning targets.

Targets are identified by their index in the canonical list.
