Functions

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 Uint32ArrayToHexString

func Uint32ArrayToHexString(value []uint32) string

func Uint32ToHexString

func Uint32ToHexString(value uint32) string

func Uint64ToHexString

func Uint64ToHexString(value uint64) string

Types

type BlockSolution

type BlockSolution [42]uint32

type Hash

type Hash [HashLength]byte

Hash represents the 32 byte Keccak256 hash of arbitrary data.

func BigToHash

func BigToHash(b *big.Int) Hash

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

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) 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.
