Function OverloadCostTracker

interpreter/runtimecost.go:215–220

OverloadCostTracker binds an overload ID to a runtime FunctionTracker implementation. OverloadCostTracker instances augment or override ActualCostEstimator decisions, allowing for versioned and/or optional cost tracking changes.

(overloadID string, fnTracker FunctionTracker)

// OverloadCostTracker instances augment or override ActualCostEstimator decisions, allowing for  versioned and/or
// optional cost tracking changes.
func OverloadCostTracker(overloadID string, fnTracker FunctionTracker) CostTrackerOption {
	return func(tracker *CostTracker) error {
		tracker.overloadTrackers[overloadID] = fnTracker
		return nil
	}
}

// FunctionTracker computes the actual cost of evaluating the functions with the given arguments and result.
