Golang PBNode Examples

Example #1

File: coding.go Project: heems/go-ipfs

// Unmarshal decodes raw data into a *Node instance.
// The conversion uses an intermediate PBNode.
func (n *Node) Unmarshal(encoded []byte) error {
	var pbn pb.PBNode
	if err := pbn.Unmarshal(encoded); err != nil {
		return fmt.Errorf("Unmarshal failed. %v", err)
	}

	pbnl := pbn.GetLinks()
	n.Links = make([]*Link, len(pbnl))
	for i, l := range pbnl {
		n.Links[i] = &Link{Name: l.GetName(), Size: l.GetTsize()}
		h, err := mh.Cast(l.GetHash())
		if err != nil {
			return fmt.Errorf("Link hash is not valid multihash. %v", err)
		}
		n.Links[i].Hash = h
	}
	sort.Stable(LinkSlice(n.Links)) // keep links sorted

	n.Data = pbn.GetData()
	return nil
}
