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.
