Types ¶

type Digest ¶

type Digest struct {
	hash.Hash
}

Digest represents the partial evaluation of a checksum.

func New ¶

func New() *Digest

New returns new hash from a given integer.

func (*Digest) Sum ¶

func (d *Digest) Sum(b []byte) Hash

Sum appends the current checksum to b and returns the Hash.

func (*Digest) WriteObject ¶

func (d *Digest) WriteObject(v interface{}) (int, error)

WriteObject adds an interface data to the running hash. It never retruns an error.

type Hash ¶

type Hash []byte

A Hash is a type for representing hash with base58 encode and decode functions.

func Decode ¶

func Decode(h string) (Hash, error)

Decode decodes the base58 encoded hash. It returns error when a hash isn't base58,encoded or hash length is invalid.

func Dump ¶

func Dump(v interface{}) Hash

Dump takes an interface and returns its hash representation.

func Int ¶

func Int(h int) Hash

Int returns a new hash from a given integer. NOTE: This method is for tests purpose only.

func Random ¶

func Random() (Hash, error)

Random returns a new random hash.

func (Hash) Equal ¶

func (h Hash) Equal(h1 Hash) bool

Equal returns a boolean reporting whether h and h1 are the same hashes.

func (Hash) IsZero ¶

func (h Hash) IsZero() bool

IsZero reports whethere h represents empty hash.

func (Hash) String ¶

func (h Hash) String() string

String returns the base58 hash representation.
