type Hash

type Hash [HashLen]byte

Hash is the hash type used in all ledger

var DummyHash Hash

DummyHash is an arbitrary hash value, used in function errors. DummyHash represents a valid hash value.

func HashInterNode

func HashInterNode(hash1 Hash, hash2 Hash) Hash

HashInterNode returns the hash value for intermediate nodes. hash1 and hash2 are fixed-length byte arrays which should be holding exactly 32 bytes each.

func HashLeaf

func HashLeaf(path Hash, value []byte) Hash

HashLeaf returns the hash value for leaf nodes. Path is a fixed-length byte array which should be holding exactly 32 bytes. Note that we don't include the keys here as they are already included in the path.

func ToHash

func ToHash(bytes []byte) (Hash, error)

ToHash converts a byte slice to Hash (fixed-length byte array). It returns an error if the slice has an invalid length.
