Types

type Address

type Address [AddressLength]byte

Address represents the 20 byte address of an Harmony account.

func BigToAddress

func BigToAddress(b *big.Int) Address

BigToAddress returns Address with byte values of b. If b is larger than len(h), b will be cropped from the left.

func BytesToAddress

func BytesToAddress(b []byte) Address

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

func HexToAddress

func HexToAddress(s string) Address

HexToAddress returns Address with byte values of s. If s is larger than len(h), s will be cropped from the left.

func (Address) Big

func (a Address) Big() *big.Int

func (Address) Bytes

func (a Address) Bytes() []byte

Bytes gets the string representation of the underlying address.

func (Address) Format

func (a Address) Format(s fmt.State, c rune)

Format implements fmt.Formatter, forcing the byte slice to be formatted as is, without going through the stringer interface used for logging.

func (Address) Hash
