Functions

func DecodeString

func DecodeString(s string) (b []byte, err error)

DecodeString parses the given hex string to bytes, it can return error if the hex string is invalid. Follows the semantic of ethereum's FromHex.

func EnsurePrefix

func EnsurePrefix(str string) string

EnsurePrefix adds the prefix (0x) to a given hex string.

func HasPrefix

func HasPrefix(str string) bool

HasPrefix returns true if the string starts with 0x.

func ParseBig

func ParseBig(s string) (*big.Int, error)

ParseBig parses the given hex string and returns error if it is invalid.

func TrimPrefix

func TrimPrefix(str string) string

TrimPrefix removes the prefix (0x) of a given hex string.

Types

type PlainHexBytes

type PlainHexBytes []byte

PlainHexBytes marshals/unmarshals as a JSON string without a 0x prefix. The empty slice marshals as "".

func (PlainHexBytes) MarshalText

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

MarshalText implements encoding.TextMarshaler

func (PlainHexBytes) String

func (b PlainHexBytes) String() string

func (*PlainHexBytes) UnmarshalJSON

func (b *PlainHexBytes) UnmarshalJSON(input []byte) (err error)

UnmarshalJSON implements json.Unmarshaler.

func (*PlainHexBytes) UnmarshalText
