Constants

const (
	HashLength      = 32

	BloomByteLength = 256
)

Lengths of hashes and addresses in bytes.

Variables

var (

)

hasherPool holds LegacyKeccak256 hashers for rlpHash.

Functions

func HexDecodeString

func HexDecodeString(s string) ([]byte, error)

HexDecodeString return rawBytes of a hex hash represent

func IsValidAddressByte

func IsValidAddressByte(data []byte) bool

Types

type Address

type Address struct {
	RawAddress [AddressLength]byte `json:"raw_address"`

BytesToAddress returns Address with value b. If b is larger than len(h), b will be cropped address the left.

func NewAddressByStr

func NewAddressByStr(s string) *Address

func (*Address) Bytes

func (a *Address) Bytes() []byte

func (*Address) MarshalJSON

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

SetBytes sets the address to the value of b. If b is larger than len(a) it will panic.

func (*Address) SetString

func (a *Address) SetString(s string)

func (*Address) Size

func (a *Address) Size() int

func (*Address) String

func (a *Address) String() string

String returns an EIP55-compliant hex string representation of the address.
