Functions

func AddZeroBytesSuffix

func AddZeroBytesSuffix(data []byte, required int) []byte

AddZeroBytesSuffix appends zero bytes such that result byte length == required

func ClearBit

func ClearBit(n byte, pos uint) byte

ClearBit clears the bit at pos in n.

func ContainsBytesInSlice

func ContainsBytesInSlice(slice [][]byte, b []byte) bool

ContainsBytesInSlice returns bool if byte slice is contained in input

func CutFromSlice

func CutFromSlice(slice [][]byte, idx int) [][]byte

CutFromSlice returns a new slice without the value at idx

func IntBytesFromString

func IntBytesFromString(s string) ([]byte, error)

IntBytesFromString return the integer base 10 string in bytes.

func IsBitSet

func IsBitSet(n byte, pos uint) bool

IsBitSet checks if the bit at position is set

func RemoveBytesFromSlice

func RemoveBytesFromSlice(slice [][]byte, b []byte) [][]byte

RemoveBytesFromSlice removes bytes b from the slice of bytes Note: all duplicates of b in slice will be removed. Note: if thee bytes b doesn't exist, same slice is returned

func RemoveZeroBytesSuffix

func RemoveZeroBytesSuffix(data []byte) []byte

RemoveZeroBytesSuffix removes zero bytes appended to the end.

func SetBit

func SetBit(n byte, pos uint) byte

SetBit sets the bit at pos in the given byte.

func SortByte32Slice

func SortByte32Slice(arr [][32]byte) [][32]byte

SortByte32Slice sorts the byte32 slices in ascending order.

func TimestampToBytes

func TimestampToBytes(tm *timestamp.Timestamp, maxTimeByteLength int) ([]byte, error)

TimestampToBytes returns encodes timestamp into a 32 byte value

Types

type BytesArray

type BytesArray [][32]byte

BytesArray is a alias for 32 byte alice

func (BytesArray) Len

func (a BytesArray) Len() int

Len returns the length of the slice

func (BytesArray) Less

func (a BytesArray) Less(i, j int) bool

Less returns true if i'th item is less than j'th else false

func (BytesArray) Swap

func (a BytesArray) Swap(i, j int)

Swap swaps the i, j values with in the array.

type HexBytes

type HexBytes []byte

HexBytes is of type bytes with JSON hex string marshaller.

func ToHexByteSlice

func ToHexByteSlice(l [][]byte) (hb []HexBytes)

ToHexByteSlice converts slicee of slice of bytes to slice of HexBytes

func (HexBytes) Bytes

func (h HexBytes) Bytes() []byte

Bytes returns a copy of the HexBytes.

func (HexBytes) MarshalJSON

func (h HexBytes) MarshalJSON() ([]byte, error)

MarshalJSON marshall bytes to hex.

func (HexBytes) String

func (h HexBytes) String() string

String returns HexBytes in string format.

func (*HexBytes) UnmarshalJSON

func (h *HexBytes) UnmarshalJSON(data []byte) error

UnmarshalJSON unmarshals hex string to bytes.

type OptionalHex

type OptionalHex struct {
	HexBytes
}

OptionalHex can have empty hex string and doesn't error.

func (*OptionalHex) UnmarshalJSON

func (o *OptionalHex) UnmarshalJSON(data []byte) error

UnmarshalJSON unmarshalls hex encoded string to bytes. if the data is an empty string, it decoded value is empty bytes.
