Functions

func InstrumentingMiddleware

func InstrumentingMiddleware(duration metrics.Histogram) endpoint.Middleware

InstrumentingMiddleware returns an endpoint middleware that records the duration of each invocation to the passed histogram. The middleware adds a single field: "success", which is "true" if no error is returned, and "false" otherwise.

func LoggingMiddleware

func LoggingMiddleware(logger log.Logger) endpoint.Middleware

LoggingMiddleware returns an endpoint middleware that logs the duration of each invocation, and the resulting error, if any.

func MakeCreateEndpoint

func MakeCreateEndpoint(s service.TransactionsService) endpoint.Endpoint

MakeCreateEndpoint returns an endpoint that invokes Create on the service.

func MakeDeleteAllEndpoint

func MakeDeleteAllEndpoint(s service.TransactionsService) endpoint.Endpoint

MakeDeleteAllEndpoint returns an endpoint that invokes DeleteAll on the service.

func MakeGetEndpoint

func MakeGetEndpoint(s service.TransactionsService) endpoint.Endpoint

MakeGetEndpoint returns an endpoint that invokes Get on the service.

Types

type CreateRequest

type CreateRequest struct {
	io.Transaction
}

CreateRequest collects the request parameters for the Create method.

type CreateResponse

type CreateResponse io.Transaction

CreateResponse collects the response parameters for the Create method.

func (CreateResponse) Failed

func (r CreateResponse) Failed() error

Failed implements Failer.

type DeleteAllRequest

type DeleteAllRequest struct{}

DeleteAllRequest struct

type DeleteAllResponse

type DeleteAllResponse struct {
	Error error `json:"error"`
}

DeleteAllResponse struct

func (DeleteAllResponse) Failed

func (r DeleteAllResponse) Failed() error

Failed reponse

type Endpoints

type Endpoints struct {
	GetEndpoint       endpoint.Endpoint
	CreateEndpoint    endpoint.Endpoint
	DeleteAllEndpoint endpoint.Endpoint
}

Endpoints collects all of the endpoints that compose a profile 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(s service.TransactionsService, mdw map[string][]endpoint.Middleware) Endpoints

New returns a Endpoints struct that wraps the provided service, and wires in all of the expected endpoint middlewares

func (Endpoints) Create

func (e Endpoints) Create(ctx context.Context, transaction io.Transaction) (t CreateResponse, error error)

Create implements Service. Primarily useful in a client.

func (Endpoints) DeleteAll

func (e Endpoints) DeleteAll(ctx context.Context) (error error)

DeleteAll implements Service

func (Endpoints) Get

func (e Endpoints) Get(ctx context.Context, uuid string) (t []io.Transaction, error error)

Get implements Service. Primarily useful in a client.

type Failure

type Failure interface {
	Failed() error
}

Failure is an interface that should be implemented by response types. Response encoders can check if responses are Failer, and if so they've failed, and if so encode them using a separate write path based on the error.

type GetRequest

type GetRequest struct {
	UUID string `json:"uuid"`
}

GetRequest collects the request parameters for the Get method.

type GetResponse

type GetResponse []io.Transaction

GetResponse collects the response parameters for the Get method.

func (GetResponse) Failed

func (r GetResponse) Failed() error

Failed implements Failer.
