Functions

func Unmarshal

func Unmarshal(data []byte, uid string, dst encoding.Builder) error

Unmarshal parses the JSON-encoded data and stores the result in dst. Node IDs are obtained from the JSON fields identified by the uid parameter. UIDs obtained from the JSON encoding must map to unique node ID values consistently across the JSON-encoded spanning tree. graph.Node values returned by dst.NewNode must satisfy StringIDSetter.

Types

type LabelSetter

	SetLabel(string)
}

LabelSetter is a graph edge that can set its label.

type StringIDSetter

type StringIDSetter interface {
	SetIDFromString(uid string) error
