// ScorePlugin is an interface that must be implemented by "Score" plugins to rank
// nodes that passed the filtering phase. Plugins that implement ScorePlugin should
// also implement SignPlugin to enable batching optimizations.
type ScorePlugin interface {
	Plugin
	// Score is called on each filtered node. It must return success and an integer
	// indicating the rank of the node. All scoring plugins must return success or
	// the pod will be rejected.
	Score(ctx context.Context, state CycleState, p *v1.Pod, nodeInfo NodeInfo) (int64, *Status)

	// ScoreExtensions returns a ScoreExtensions interface if it implements one, or nil if does not.
