Functions

func AddSupportToChooser

func AddSupportToChooser(existing traversal.LinkTargetNodePrototypeChooser) traversal.LinkTargetNodePrototypeChooser

AddSupportToChooser takes an existing node prototype chooser and subs in IAVLNode for the cosmos smt multicodec code.

func AppendEncode

func AppendEncode(enc []byte, inNode ipld.Node) ([]byte, error)

AppendEncode is like Encode, but it uses a destination buffer directly. This means less copying of bytes, and if the destination has enough capacity, fewer allocations.

func Decode

func Decode(na ipld.NodeAssembler, in io.Reader) error

Decode provides an IPLD codec decode interface for Tendermint IAVL nodes This function is registered via the go-ipld-prime link loader for multicodec code XXX when this package is invoked via init.

func DecodeBytes

func DecodeBytes(na ipld.NodeAssembler, src []byte) error

DecodeBytes is like DecodeTrieNode, but it uses an input buffer directly. Decode will grab or read all the bytes from an io.Reader anyway, so this can save having to copy the bytes or create a bytes.Buffer.

func Decoder

func Decoder(na ipld.NodeAssembler, r io.Reader) error

Deprecated: use Decode instead.

func Encode

func Encode(node ipld.Node, w io.Writer) error

Encode provides an IPLD codec encode interface for Tendermint IAVL node IPLDs. This function is registered via the go-ipld-prime link loader for multicodec code XXXX when this package is invoked via init.

func Encoder

func Encoder(inNode ipld.Node, w io.Writer) error

Deprecated: use Encode instead.

func Marshal

func Marshal(inNode ipld.Node, w io.Writer) error

Deprecated: use Encode instead.

func Unmarshal

func Unmarshal(na ipld.NodeAssembler, r io.Reader) error

Deprecated: use Decode instead.

Types

type Node

type Node struct {
	// contains filtered or unexported fields
}

Node represents a node in a IAVL tree.

type NodeKind

type NodeKind string

const (
	INNER_NODE NodeKind = "inner"
	LEAF_NODE  NodeKind = "leaf"
)

func NodeAndKind

func NodeAndKind(node ipld.Node) (ipld.Node, NodeKind, error)

NodeAndKind returns the node and its kind

func (NodeKind) String

func (n NodeKind) String() string
