Types

type Uint128

type Uint128 struct {
	// contains filtered or unexported fields
}

A Uint128 is an unsigned 128-bit number.

var Zero Uint128

Zero is a zero-valued uint128.

func From64

func From64(v uint64) Uint128

From64 converts v to a Uint128 value.

func FromBig

func FromBig(i *big.Int) (u Uint128)

FromBig converts i to a Uint128 value. It panics if i is negative or overflows 128 bits.

func FromBytes

func FromBytes(b []byte) Uint128

FromBytes converts b to a Uint128 value.

func FromString

func FromString(s string) (Uint128, error)

func New

func New(lo, hi uint64) Uint128

New returns the Uint128 value (lo,hi).

func (Uint128) Add

func (u Uint128) Add(v Uint128) Uint128

Add returns u+v.

func (Uint128) Add64

func (u Uint128) Add64(v uint64) Uint128

Add64 returns u+v.

func (Uint128) And

func (u Uint128) And(v Uint128) Uint128

And returns u&v.

func (Uint128) And64

func (u Uint128) And64(v uint64) Uint128

And64 returns u&v.

func (Uint128) Big

func (u Uint128) Big() *big.Int

Big returns u as a *big.Int.

func (Uint128) Cmp

func (u Uint128) Cmp(v Uint128) int

Cmp compares u and v and returns:

-1 if u <  v
 0 if u == v
+1 if u >  v

func (Uint128) Cmp64

func (u Uint128) Cmp64(v uint64) int

Cmp64 compares u and v and returns:

-1 if u <  v
 0 if u == v
+1 if u >  v

func (Uint128) Div

func (u Uint128) Div(v Uint128) Uint128

Div returns u/v.

func (Uint128) Div64

func (u Uint128) Div64(v uint64) Uint128

Div64 returns u/v.

func (Uint128) Equals

func (u Uint128) Equals(v Uint128) bool

Equals returns true if u == v.

Uint128 values can be compared directly with ==, but use of the Equals method is preferred for consistency.

func (Uint128) Equals64

func (u Uint128) Equals64(v uint64) bool

Equals64 returns true if u == v.

func (Uint128) IsZero

func (u Uint128) IsZero() bool

IsZero returns true if u == 0.

func (Uint128) Lsh

func (u Uint128) Lsh(n uint) (s Uint128)

Lsh returns u<<n.

func (Uint128) Mul

func (u Uint128) Mul(v Uint128) Uint128

Mul returns u*v.

func (Uint128) Mul64

func (u Uint128) Mul64(v uint64) Uint128

Mul64 returns u*v.

func (Uint128) Or

func (u Uint128) Or(v Uint128) Uint128

Or returns u|v.

func (Uint128) Or64

func (u Uint128) Or64(v uint64) Uint128

Or64 returns u|v.

func (Uint128) PutBytes

func (u Uint128) PutBytes(b []byte)

PutBytes stores u in b in little-endian order. It panics if len(b) < 16.

func (Uint128) QuoRem

func (u Uint128) QuoRem(v Uint128) (q, r Uint128)

QuoRem returns q = u/v and r = u%v.

func (Uint128) QuoRem64

func (u Uint128) QuoRem64(v uint64) (q Uint128, r uint64)

QuoRem64 returns q = u/v and r = u%v.

func (Uint128) Rsh

func (u Uint128) Rsh(n uint) (s Uint128)

Rsh returns u>>n.

func (Uint128) String

func (u Uint128) String() string
