Variables

var (
	ErrDivideByZero = errors.New("can't divide by zero")

Functions

func NewBasicService

func NewBasicService() basicService

NewBasicService returns a naïve, stateless implementation of Service.

Types

type Service

type Service interface {
	// Divide two integers, a/b
	Divide(ctx context.Context, a, b float64) (float64, error)
	// Max two integers, returns the greater value of a and b
	Max(ctx context.Context, a, b float64) (float64, error)
	// Min two integers, returns the lesser value of a and b
	Min(ctx context.Context, a, b float64) (float64, error)
	// Multiply two integers, a*b
	Multiply(ctx context.Context, a, b float64) (float64, error)
	// Pow two integers, a^b
	Pow(ctx context.Context, a, b float64) (float64, error)
	// Subtract two integers, a-b
	Subtract(ctx context.Context, a, b float64) (float64, error)
	// Sums two integers. a+b
	Sum(ctx context.Context, a, b float64) (float64, error)
}

Service describes a service that adds things together.
