type Uint128 struct {
	Hi, Lo uint64
}

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

func FromBytes(b []byte) Uint128

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

func FromInts(hi uint64, lo uint64) Uint128

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

func FromString(s string) (Uint128, error)

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

func (u Uint128) Add(n Uint128) Uint128

Add returns a new Uint128 incremented by n.

func (u Uint128) And(o Uint128) Uint128

And returns a new Uint128 that is the bitwise AND of two Uint128 values.

func (u Uint128) Compare(o Uint128) int

Compare compares the two Uint128.

func (u Uint128) Equal(o Uint128) bool

Equal returns whether or not the Uint128 are equivalent.

func (u Uint128) GetBytes() []byte

GetBytes returns a big-endian byte representation.

func (u Uint128) Or(o Uint128) Uint128

Or returns a new Uint128 that is the bitwise OR of two Uint128 values.

func (u Uint128) String() string

String returns a hexadecimal string representation.

func (u Uint128) Sub(n Uint128) Uint128

Sub returns a new Uint128 decremented by n.

func (u Uint128) Xor(o Uint128) Uint128

Xor returns a new Uint128 that is the bitwise XOR of two Uint128 values.
