Functions

func IsPositive

func IsPositive(b BigUInt) bool

func IsZero

func IsZero(b BigUInt) bool

Types

type BigUInt

type BigUInt struct {
	*big.Int
}

BigUInt is a simple wrapper on bigint to support marshaling to protobufs

func BigZero

func BigZero() *BigUInt

func (*BigUInt) Add

func (b *BigUInt) Add(x, y *BigUInt) *BigUInt

Add sets z to the sum x+y and returns z.

func (*BigUInt) Cmp

func (b *BigUInt) Cmp(i *BigUInt) int

Cmp compares x and y and returns:

-1 if x <  y
 0 if x == y
+1 if x >  y

func (*BigUInt) Div

func (b *BigUInt) Div(x, y *BigUInt) *BigUInt

Div sets z to the quotient x/y for y != 0 and returns z. If y == 0, a division-by-zero run-time panic occurs. Div implements Euclidean division (unlike Go); see DivMod for more details.

func (*BigUInt) Exp

func (b *BigUInt) Exp(x, y, m *BigUInt) *BigUInt

Exp sets z = x**y mod |m| (i.e. the sign of m is ignored), and returns z. If y <= 0, the result is 1 mod |m|; if m == nil or m == 0, z = x**y.

Modular exponentation of inputs of a particular size is not a cryptographically constant-time operation.

func (*BigUInt) Marshal

func (b *BigUInt) Marshal() ([]byte, error)

Marshal converts to a byte buffer for protobufs

func (*BigUInt) Mul

func (b *BigUInt) Mul(x, y *BigUInt) *BigUInt

Mul sets z to the product x*y and returns z.

func (*BigUInt) Size

func (b *BigUInt) Size() int

Size returns the length of the protobuf data

func (*BigUInt) Sub

func (b *BigUInt) Sub(x, y *BigUInt) *BigUInt

Sub sets z to the difference x-y and returns z.

func (*BigUInt) Uint64

func (b *BigUInt) Uint64() uint64

func (*BigUInt) Unmarshal

func (b *BigUInt) Unmarshal(by []byte) error

Unmarshal unmarshals protobuf data

type LocalAddress

type LocalAddress []byte

func (LocalAddress) Compare

func (a LocalAddress) Compare(other LocalAddress) int

func (LocalAddress) Hex

func (a LocalAddress) Hex() string

From ethereum with finalized sha3 Note: only works with addresses up to 256 bit

func (LocalAddress) Marshal

func (a LocalAddress) Marshal() ([]byte, error)

Marshal converts to a byte buffer for protobufs

func (LocalAddress) Size

func (a LocalAddress) Size() int

Size returns the number of bytes for deterministic marshaling

func (LocalAddress) String

func (a LocalAddress) String() string

func (*LocalAddress) Unmarshal

func (a *LocalAddress) Unmarshal(data []byte) error

Unmarshal unmarshals protobuf data
