Method comparePrintableName

internal/graph/graph.go:200–212

comparePrintableName compares NodeInfo lexicographically the same way as `i.PrintableName() < right.PrintableName()`, but much more performant.

(right NodeInfo)

// comparePrintableName compares NodeInfo lexicographically the same way as `i.PrintableName() < right.PrintableName()`, but much more performant.
func (i *NodeInfo) comparePrintableName(right NodeInfo) (equal bool, less bool) {
	if right == *i {
		return true, false
	}

	if i.Address != 0 && right.Address != 0 && i.Address != right.Address {
		// comparing ints directly is the same as comparing padded hex from fmt.Sprintf("%016x", Address)
		return false, i.Address < right.Address
	}

	// fallback
	return false, i.PrintableName() < right.PrintableName()
}

// NodeMap maps from a node info struct to a node. It is used to merge
// report entries with the same info.
