Types

type Address

type Address [AddressLength]byte

Address is wallet address.

func BytesToAddress

func BytesToAddress(bytes []byte) (a Address, err error)

BytesToAddress create a new address from raw bytes.

func (Address) Bytes

func (a Address) Bytes() []byte

Bytes gets the byte representation of the underlying address.

func (Address) Hex

func (a Address) Hex() string

Hex gets string representation of the underlying address.

func (Address) MarshalJSON

func (a Address) MarshalJSON() ([]byte, error)

MarshalJSON implements json marshalling interface.

func (*Address) UnmarshalJSON

func (a *Address) UnmarshalJSON(bytes []byte) error

UnmarshalJSON unmarshal JSON into Address.

type Hash

type Hash [HashLength]byte

Hash represents the 32 byte Keccak256 hash of arbitrary data.

func BytesToHash

func BytesToHash(bytes []byte) (h Hash, err error)

BytesToHash create a new hash from raw bytes.

func (Hash) Bytes

func (h Hash) Bytes() []byte
