Root nodes are indexed separately by their version

Functions ¶

func Commit ¶

func Commit(batches []dbm.Batch) error

func GetLatestVersion ¶

func GetLatestVersion(db dbm.DB) int64

func OpenApplicationDB ¶

func OpenApplicationDB(rootDir string) (dbm.DB, error)

func OpenBlockStoreDB ¶

func OpenBlockStoreDB(rootDir string) (dbm.DB, error)

func OpenStateDB ¶

func OpenStateDB(rootDir string) (dbm.DB, error)

func PrefixDB ¶

func PrefixDB(key *sdk.KVStoreKey, originDB dbm.DB) *dbm.PrefixDB

Types ¶

type Node ¶

type Node struct {
	Hash      []byte
	LeftHash  []byte
	RightHash []byte
	Version   int64
	// contains filtered or unexported fields
}

Node represents a node in a Tree.

func MakeNode ¶

func MakeNode(buf []byte) (*Node, error)

MakeNode constructs an *Node from an encoded byte slice.

The new node doesn't have its hash saved or set. The caller must set it afterwards.

func NewNode ¶

func NewNode(key []byte, value []byte, version int64) *Node

NewNode returns a new node from a key, value and version.
