Types

type MathOpRequest

type MathOpRequest struct {
	A, B float64
}

MathOpRequest collects the request parameters for the math methods.

type MathOpResponse

type MathOpResponse struct {
	V   float64 `json:"v"`
	Err error   `json:"-"` // should be intercepted by Failed/errorEncoder
}

MathOpResponse collects the response values for the math methods.

func (MathOpResponse) Failed

func (r MathOpResponse) Failed() error

Failed implements endpoint.Failer.

type Set

type Set struct {
	DivideEndpoint   endpoint.Endpoint
	MaxEndpoint      endpoint.Endpoint
	MinEndpoint      endpoint.Endpoint
	MultiplyEndpoint endpoint.Endpoint
	PowEndpoint      endpoint.Endpoint
	SubtractEndpoint endpoint.Endpoint
	SumEndpoint      endpoint.Endpoint
}

Set collects all of the endpoints that compose an add service. It's meant to be used as a helper struct, to collect all of the endpoints into a single parameter.

func New

func New(svc mathservice2.Service, logger log.Logger) Set

New returns a Set that wraps the provided server, and wires in all of the expected endpoint middlewares via the various parameters.

func (Set) Divide

func (s Set) Divide(ctx context.Context, a, b float64) (float64, error)

Divide implements the service interface, so Set may be used as a service. This is primarily useful in the context of a client library.

func (Set) Max

func (s Set) Max(ctx context.Context, a, b float64) (float64, error)

Max implements the service interface, so Set may be used as a service. This is primarily useful in the context of a client library.

func (Set) Min

func (s Set) Min(ctx context.Context, a, b float64) (float64, error)

Min implements the service interface, so Set may be used as a service. This is primarily useful in the context of a client library.

func (Set) Multiply

func (s Set) Multiply(ctx context.Context, a, b float64) (float64, error)

Multiply implements the service interface, so Set may be used as a service. This is primarily useful in the context of a client library.

func (Set) Pow

func (s Set) Pow(ctx context.Context, a, b float64) (float64, error)

Pow implements the service interface, so Set may be used as a service. This is primarily useful in the context of a client library.

func (Set) Subtract

func (s Set) Subtract(ctx context.Context, a, b float64) (float64, error)

Subtract implements the service interface, so Set may be used as a service. This is primarily useful in the context of a client library.

func (Set) Sum

func (s Set) Sum(ctx context.Context, a, b float64) (float64, error)

Sum implements the service interface, so Set may be used as a service. This is primarily useful in the context of a client library.
