Types

type Uint128

type Uint128 struct {
	Hi, Lo uint64
}

Uint128 is a big-endian 128 bit unsigned integer which wraps two uint64s.

func FromBytes

func FromBytes(b []byte) Uint128

FromBytes parses the byte slice as a 128 bit big-endian unsigned integer.

func FromInts

func FromInts(hi uint64, lo uint64) Uint128

FromInts takes in two unsigned 64-bit integers and constructs a Uint128.

func FromString

func FromString(s string) (Uint128, error)

FromString parses a hexadecimal string as a 128-bit big-endian unsigned integer.

func (Uint128) Add

func (u Uint128) Add(n uint64) Uint128

Add returns a new Uint128 incremented by n.

func (Uint128) GetBytes

func (u Uint128) GetBytes() []byte

GetBytes returns a big-endian byte representation.

func (Uint128) String

func (u Uint128) String() string

String returns a hexadecimal string representation.

func (Uint128) Sub

func (u Uint128) Sub(n uint64) Uint128

Sub returns a new Uint128 decremented by n.
