type TargeterConfig

type TargeterConfig struct {
	// VdrAlloc is the amount of the resource to split over validators, weighted
	// by stake.
	VdrAlloc float64 `json:"vdrAlloc"`

	// MaxNonVdrUsage is the amount of the resource which, if utilized, will
	// result in allocations being based only on the stake weighted allocation.
	MaxNonVdrUsage float64 `json:"maxNonVdrUsage"`

	// MaxNonVdrNodeUsage is the amount of the resource to allocate to a node
	// before adding the stake weighted allocation.

	TotalUsage() float64
	// Returns the duration between [now] and when the usage of [nodeID] reaches
	// [value], assuming that the node uses no more resources.
	// If the node's usage isn't known, or is already <= [value], returns the
	// zero duration.
	TimeUntilUsage(nodeID ids.NodeID, now time.Time, value float64) time.Duration
