Types ¶

type DAGService ¶

type DAGService struct {
	Blocks *blocks.BlockService
}

An IPFS Merkle DAG service. the root is virtual (like a forest) stores nodes' data in a blockService

func (*DAGService) Get ¶

func (n *DAGService) Get(k u.Key) (*Node, error)

func (*DAGService) Put ¶

func (n *DAGService) Put(nd *Node) (u.Key, error)

type Link ¶

type Link struct {
	// utf string name. should be unique per object
	Name string // utf8

	// cumulative size of target object
	Size uint64

	// multihash of the target object
	Hash mh.Multihash

	// a ptr to the actual node for graph manipulation
	Node *Node
}

An IPFS Merkle DAG Link

type Node ¶

type Node struct {
	Links []*Link
	Data  []byte
	// contains filtered or unexported fields
}

A node in the IPFS Merkle DAG. nodes have opaque data and a set of navigable links.

func Decoded ¶

func Decoded(encoded []byte) (*Node, error)

func (*Node) AddNodeLink ¶

func (n *Node) AddNodeLink(name string, that *Node) error

func (*Node) Encoded ¶

func (n *Node) Encoded(force bool) ([]byte, error)

func (*Node) Key ¶

func (n *Node) Key() (u.Key, error)

func (*Node) Marshal ¶

func (n *Node) Marshal() ([]byte, error)

func (*Node) MarshalTo ¶

func (n *Node) MarshalTo(encoded []byte) error

func (*Node) Multihash ¶

func (n *Node) Multihash() (mh.Multihash, error)

func (*Node) Size ¶

func (n *Node) Size() (uint64, error)

func (*Node) Unmarshal ¶

func (n *Node) Unmarshal(encoded []byte) error

type NodeMap ¶

type NodeMap map[u.Key]*Node

can't use []byte/Multihash for keys :( so have to convert Multihash bytes to string

type PBLink ¶

type PBLink struct {
	// multihash of the target object
	Hash []byte `protobuf:"bytes,1,opt" json:"Hash,omitempty"`
	// utf string name. should be unique per object
	Name *string `protobuf:"bytes,2,opt" json:"Name,omitempty"`
	// cumulative size of target object
	Tsize            *uint64 `protobuf:"varint,3,opt" json:"Tsize,omitempty"`
	XXX_unrecognized []byte  `json:"-"`
}

	// opaque user data
	Data             []byte `protobuf:"bytes,1,opt" json:"Data,omitempty"`
