Functions

func FromHex

func FromHex(data string) []byte

func HashesToBytesS

func HashesToBytesS(hashes []Hash) [][]byte

func IsZeroHash

func IsZeroHash(h Hash) bool

func ToHex

func ToHex(data []byte) string

Types

type Address

type Address [AddressLength]byte

Address represents the 20 byte address of an Ethereum account.

func BytesToAddress

func BytesToAddress(b []byte) Address

func (Address) Bytes

func (a Address) Bytes() []byte

func (*Address) SetBytes

func (a *Address) SetBytes(b []byte)

SetBytes Sets the hash to the value of b. If b is larger than len(h), 'b' will be cropped (from the left).

func (Address) String

func (a Address) String() string

type Hash

type Hash [HashLength]byte

Hash represents the 32 byte sha3-256 hash of arbitrary data.

func BytesSToHashes

func BytesSToHashes(bytesS [][]byte) []Hash

func BytesToHash

func BytesToHash(b []byte) Hash

func BytesToSha3

func BytesToSha3(data []byte) Hash

BytesToSha3 creates a new SHA3-256 hash.

func ProtoToSha3

func ProtoToSha3(in proto.Message) (Hash, error)

func (Hash) Bytes

func (h Hash) Bytes() []byte

func (*Hash) SetBytes

func (h *Hash) SetBytes(b []byte)

SetBytes Sets the hash to the value of b. If b is larger than len(h), 'b' will be cropped (from the left).

func (Hash) String

func (h Hash) String() string
