Constants

const HashSize = 32

HashSize of array used to store hashes.

const MaxHashStringSize = HashSize * 2

MaxHashStringSize is the maximum length of a Hash hash string.

Variables

var ErrHashStrSize = fmt.Errorf("max hash string length is %v bytes", MaxHashStringSize)

ErrHashStrSize describes an error that indicates the caller specified a hash string that has too many characters.

Functions

func Decode

func Decode(dst *Hash, src string) error

Decode decodes the byte-reversed hexadecimal string encoding of a Hash to a destination.

func IsEmpty

func IsEmpty(channelId Hash) bool

Types

type ChainHash

type ChainHash string

type Hash

type Hash [HashSize]byte

Hash is used in several of the bitcoin messages and common structures. It typically represents the double sha256 of data.

func NewHash

func NewHash(newHash []byte) (*Hash, error)

NewHash returns a new Hash from a byte slice. An error is returned if the number of bytes passed in is not HashSize.

func NewHashFromStr

func NewHashFromStr(hash string) (*Hash, error)

NewHashFromStr creates a Hash from a hash string. The string should be the hexadecimal string of a byte-reversed hash, but any missing characters result in zero padding at the end of the Hash.

func (*Hash) IsEqual

func (hash *Hash) IsEqual(target *Hash) bool

IsEqual returns true if target is the same as hash.

func (*Hash) SetBytes

func (hash *Hash) SetBytes(newHash []byte) error

SetBytes sets the bytes which represent the hash. An error is returned if the number of bytes passed in is not HashSize.

func (Hash) String

func (hash Hash) String() string

String returns the Hash as the hexadecimal string of the byte-reversed hash.

type Point

type Point string

type Signature

type Signature []byte
