Constants

const (
	// HashLength is the expected length of the hash
	HashLength = 32
	// AddressLength
	AddressLength = 20
)

Lengths of hashes and addresses in bytes.

const NetworkIDPrefix = "snode:"

Functions

func Bytes2Hex

func Bytes2Hex(d []byte) string

Bytes2Hex returns the hexadecimal encoding of d.

func Encode

func Encode(b []byte) string

Encode encodes b as a hex string with 0x prefix.

func FromHex

func FromHex(s string) []byte

FromHex returns the bytes represented by the hexadecimal string s. s may be prefixed with "0x".

func Hex2Bytes

func Hex2Bytes(str string) []byte

Hex2Bytes returns the bytes represented by the hexadecimal string str.

func IsHexAddress

func IsHexAddress(s string) bool

IsHexAddress verifies whether a string can represent a valid hex-encoded Ethereum address or not.

func P2pAddressToBech

func P2pAddressToBech(p2pAddr Address) (string, error)

Types

type Address

type Address [AddressLength]byte

Address

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 P2pAddressFromBech

func P2pAddressFromBech(str string) (Address, error)

func WalletAddressFromBech

func WalletAddressFromBech(str string) (Address, error)

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) 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) 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) String

func (a Address) String() string

String implements fmt.Stringer.

func (Address) ToBech

func (a Address) ToBech(hrp string) (string, error)

type Hash

type Hash [HashLength]byte

Hash represents the 32 byte Keccak256 hash of arbitrary data.

func BytesToHash

func BytesToHash(b []byte) Hash

BytesToHash sets b to hash. If b is larger than len(h), b will be cropped from the left.

func HexToHash

func HexToHash(s string) Hash

HexToHash sets byte representation of s to hash. If b is larger than len(h), b will be cropped from the left.

func (Hash) Big

func (h Hash) Big() *big.Int

Big converts a hash to a big integer.

func (Hash) Bytes

func (h Hash) Bytes() []byte

Bytes gets the byte representation of the underlying hash.

func (Hash) Float64

func (h Hash) Float64() float64

func (Hash) Format

func (h Hash) 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 (Hash) Hex

func (h Hash) Hex() string

Hex converts a hash to a hex string.

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

String implements the stringer interface and is used also by the logger when doing full logging into a file.

func (Hash) TerminalString

func (h Hash) TerminalString() string

TerminalString implements log.TerminalStringer, formatting a string for console output during logging.

type NetworkID

type NetworkID struct {
	P2pAddress     string
	NetworkAddress string
}

func IDFromString

func IDFromString(idString string) (*NetworkID, error)

func (NetworkID) String

func (n NetworkID) String() string
