Types

	Update(*kueue.ClusterQueue) error
	// Cohort returns the Cohort of this ClusterQueue.
	Cohort() string

	// AddFromLocalQueue pushes all workloads belonging to this queue to
	// the ClusterQueue. If at least one workload is added, returns true.
	// Otherwise returns false.
	AddFromLocalQueue(*LocalQueue) bool
	// DeleteFromLocalQueue removes all workloads belonging to this queue from
	// the ClusterQueue.
	DeleteFromLocalQueue(*LocalQueue)

	// RequeueIfNotPresent inserts a workload that was not
	// admitted back into the ClusterQueue. If the boolean is true,
	// the workloads should be put back in the queue immediately,
	// because we couldn't determine if the workload was admissible
	// in the last cycle. If the boolean is false, the implementation might
	// choose to keep it in temporary placeholder stage where it doesn't
	// compete with other workloads, until cluster events free up quota.
	// The workload should not be reinserted if it's already in the ClusterQueue.
	// Returns true if the workload was inserted.

	// workloads that were already tried and are waiting for cluster conditions
	// to change to potentially become admissible.
