Functions ¶

func Encode ¶

func Encode(b []byte) string

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

func EncodeTs ¶

func EncodeTs(number uint64) []byte

EncodeTs encodes a TimeStamp (BlockNumber or TxNumber or other uin64) as big endian

func FromHex ¶

func FromHex(s string) []byte

func Has0xPrefix ¶

func Has0xPrefix(str string) bool

Has0xPrefix validates str begins with '0x' or '0X'.

func Hex2Bytes ¶

func Hex2Bytes(str string) []byte

Hex2Bytes returns the bytes represented by the hexadecimal string str.

func IsHex ¶

func IsHex(str string) bool

IsHex validates whether each byte is valid hexadecimal string.

func MustDecodeHex ¶

func MustDecodeHex(in string) []byte

func MustDecodeString ¶

func MustDecodeString(s string) []byte

func UnmarshalFixedJSON ¶

func UnmarshalFixedJSON(typ reflect.Type, input, out []byte) error

UnmarshalFixedJSON decodes the input as a string with 0x prefix. The length of out determines the required input length. This function is commonly used to implement the UnmarshalJSON method for fixed-size types.

func UnmarshalFixedText ¶

func UnmarshalFixedText(typeName string, input, out []byte) error

UnmarshalFixedText decodes the input as a string with 0x prefix. The length of out determines the required input length. This function is commonly used to implement the UnmarshalText method for fixed-size types.

Types ¶

type Bytes ¶

type Bytes []byte

Bytes marshals/unmarshals as a JSON string with 0x prefix. The empty slice marshals as "0x".

func (Bytes) MarshalText ¶

func (b Bytes) MarshalText() ([]byte, error)

MarshalText implements encoding.TextMarshaler

func (Bytes) String ¶

func (b Bytes) String() string

String returns the hex encoding of b.

func (*Bytes) UnmarshalJSON ¶

func (b *Bytes) UnmarshalJSON(input []byte) error

UnmarshalJSON implements json.Unmarshaler.

func (*Bytes) UnmarshalText ¶

func (b *Bytes) UnmarshalText(input []byte) error

UnmarshalText implements encoding.TextUnmarshaler.
