Types

type AddArg 

type AddArg struct {
	A int `json:"a"`
	B int `json:"b"`
}

type AddReply 

type AddReply int

type BigMulArg 

type BigMulArg struct {
	A *big.Int `json:"a"`
	B *big.Int
}

type BigMulReply 

type BigMulReply big.Int

type Calculator 

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

func (*Calculator) Add 

func (c *Calculator) Add(argA, argB int) int

Add adds two integers together.

func (*Calculator) BigMul 

func (c *Calculator) BigMul(argA, argB *big.Int) *big.Int

BigMul returns a new *big.Int, the product of argA and argB.

func (*Calculator) ConstructCircle 

func (c *Calculator) ConstructCircle(x, y float64, radius float64) *fakegeometry.Circle

ConstructCircle makes a circle. It returns an unnamed external package type pointer.

func (*Calculator) Div 

func (c *Calculator) Div(int, int) error

Div doesn's actually do anything. You should use Mul instead. Warning: Deprecated.

func (*Calculator) GetRecord 

func (c *Calculator) GetRecord() *Record

GetRecord returns a special data type with a total use count and a tally of done operations.

func (*Calculator) GuessAreaOfCircle 

func (c *Calculator) GuessAreaOfCircle(*Pi, *fakegeometry.Circle) float64

GuessAreaOfCircle returns a pretty good guess. It accepts an unnamed external package pointer as its only argument.

func (*Calculator) HasBatteries 

func (c *Calculator) HasBatteries() bool

HasBatteries checks whether the calculator has batteries.

func (*Calculator) History 

func (c *Calculator) History() []HistoryItem

History returns the complete history of the calculator since it was last reset.

func (*Calculator) IsZero 

func (c *Calculator) IsZero(argA int) bool

IsZero tells you if a number is zero. People love this one.

func (*Calculator) Last 

func (c *Calculator) Last() (calculation *HistoryItem)

Last returns the last command the calculator did.

func (*Calculator) LatestError 

func (c *Calculator) LatestError() (error, bool)

Latest error returns the latest error the calculator encountered. It is not usually an RPC-eligible method because it returns an error as the first value (go-ethereum), and returns 2 values (standard).

func (*Calculator) Mul 

func (c *Calculator) Mul(argA int, argB int) (int, error)

Mul multiplies the arguments.

func (*Calculator) Reset 

func (c *Calculator) Reset()

Reset clears the calculator memory.

func (*Calculator) SumWithContext 

func (c *Calculator) SumWithContext(ctx context.Context, number int) (int, error)

AddWithContext has context.Context as its first parameter, which ethereum/go-ethereum/rpc will skip.

func (*Calculator) ThreePseudoRandomNumbers 

func (c *Calculator) ThreePseudoRandomNumbers() (int, int, int)

ThreeRandomNumbers returns three psdeuo-random numbers.

type CalculatorRPC 

type CalculatorRPC struct {
	*Calculator
}

CalculatorRPC wraps Calculator to provide an standard RPC service (a receiver that satifies method signature requirements for standard rpc package).

func (*CalculatorRPC) Add 

func (c *CalculatorRPC) Add(arg AddArg, reply *AddReply) error

Add sums the A and B fields of the argument.

func (*CalculatorRPC) BigMul 

func (c *CalculatorRPC) BigMul(arg BigMulArg, reply *BigMulReply) error

func (*CalculatorRPC) BrokenReset 

func (c *CalculatorRPC) BrokenReset()

func (*CalculatorRPC) Div 

func (c *CalculatorRPC) Div(arg DivArg, reply *DivReply) error

Div is deprecated. Use Mul instead.

func (*CalculatorRPC) HasBatteries 

func (c *CalculatorRPC) HasBatteries(arg HasBatteriesArg, reply *HasBatteriesReply) error

HasBatteries returns true if the calculator has batteries.

func (*CalculatorRPC) IsZero 

func (c *CalculatorRPC) IsZero(big.Int, *IsZeroArg) error

IsZero has throwaway parameters.

func (*CalculatorRPC) Mul 

func (c *CalculatorRPC) Mul(argA int, argB int) (int, error)

Mul multiplies the arguments, but WILL NOT be eligible in standard RPC; wrong signature.

type DivArg 

type DivArg struct {
	A int `json:"a"`
	B int `json:"b"`
}

type DivReply 

type DivReply int

type HasBatteriesArg 

type HasBatteriesArg string

type HasBatteriesReply 

type HasBatteriesReply bool

type HistoryItem 

type HistoryItem struct {
	Method string
	Args   []interface{}
}

type IsZeroArg 

type IsZeroArg bool

type OpTally 

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

type Pi 

type Pi struct{}

type Record 

type Record struct {
	Count      int `json:"total_calculator_use"`
	Operations OpTally
}
