Address represents the 20 byte address of an Ethereum 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 StringToAddress

func StringToAddress(s string) Address

func (Address) Big

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

Big converts an address to a big integer.

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

func (a Address) Hash() Hash

Hash converts an address to a hash by left-padding it with zeros.

func (Address) Hex

func (a Address) Hex() string

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

func (Address) MarshalText

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

MarshalText returns the hex representation of a.

func (*Address) Scan

func (a *Address) Scan(src interface{}) error

Scan implements Scanner for database/sql.

func (*Address) Set

func (a *Address) Set(other Address)

Sets a to other

func (*Address) SetBytes

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

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)

Set string `s` to a. If s is larger than len(a) it will panic

func (Address) Str

func (a Address) Str() string

Str gets the string representation of the underlying address

func (Address) String

func (a Address) String() string

String implements the stringer interface and is used also by the logger.
