Invalid competitive-selection configuration or input.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NoCandidates

At least one candidate is required by this selection mode.

CandidateOutOfRange

A candidate index is outside the admitted candidate set.

SeatOutOfRange

A seat index is outside the admitted seat set.

SeatAlreadyAllocated

The selected seat already holds an allocation.

NoCandidateAvailable

Every candidate is currently allocated to another seat.

ScoreOutOfRange

A score is outside the admitted score domain.

ScoreCountMismatch

A score replacement has a different candidate count.

WeightTotalBelowReservedFloor

The weight total is smaller than the reserved unit per candidate.

WeightTotalOutOfRange

The weight total exceeds the verified arithmetic ceiling.

MaxScoreOutOfRange

The declared maximum score exceeds the verified arithmetic ceiling.

AllocationComplete

Every available soft-selection unit has already been assigned.
