Functions ¶

func BytesToAddress ¶

func BytesToAddress(b []byte) types.Address

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

func BytesToHash ¶

func BytesToHash(b []byte) types.Hash

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

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 HashAlg ¶ added in v1.0.0

func HashAlg() hash.Hash

get hash algorithm by global config

func HashToBytes ¶

func HashToBytes(hash types.Hash) []byte

HashToBytes convert hash to []byte

func HeaderHash ¶

func HeaderHash(block *types.Block) (hash types.Hash)

HeaderHash calculate block's hash

func Hex2Bytes ¶

func Hex2Bytes(str string) []byte

Hex2Bytes returns the bytes represented by the hexadecimal string str.

func HexToAddress ¶

func HexToAddress(s string) types.Address

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

func HexToHash ¶

func HexToHash(s string) types.Hash

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

func Serialize ¶

func Serialize(w io.Writer, f *int64) error

func TxHash ¶

func TxHash(tx *types.Transaction) (hash types.Hash)

TxHash calculate tx's hash

func WriteUint32 ¶

func WriteUint32(writer io.Writer, val uint32) error

func WriteUint64 ¶

func WriteUint64(writer io.Writer, val uint64) error

func WriteVarBytes ¶

func WriteVarBytes(writer io.Writer, value []byte) error

func WriteVarUint ¶

func WriteVarUint(writer io.Writer, value uint64) error

Types ¶

type DataEntryPrefix ¶

type DataEntryPrefix byte
