Functions ¶
func InstrumentingMiddleware ¶
func InstrumentingMiddleware[REQ any, RES any](duration metrics.Histogram) endpoint.Middleware[REQ, RES]
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 ¶
LoggingMiddleware returns an endpoint middleware that logs the duration of each invocation, and the resulting error, if any.
func MakeConcatEndpoint ¶
func MakeConcatEndpoint(s addservice.Service) endpoint.Endpoint[ConcatRequest, ConcatResponse]
MakeConcatEndpoint constructs a Concat endpoint wrapping the service.
func MakeSumEndpoint ¶
func MakeSumEndpoint(s addservice.Service) endpoint.Endpoint[SumRequest, SumResponse]
MakeSumEndpoint constructs a Sum endpoint wrapping the service.
Types ¶
type ConcatRequest ¶
type ConcatRequest struct {
A, B string
}
ConcatRequest collects the request parameters for the Concat method.
type ConcatResponse ¶
ConcatResponse collects the response values for the Concat method.
func (ConcatResponse) Failed ¶
func (r ConcatResponse) Failed() error
Failed implements endpoint.Failer.
type Set ¶
type Set struct {
SumEndpoint endpoint.Endpoint[SumRequest, SumResponse]
ConcatEndpoint endpoint.Endpoint[ConcatRequest, ConcatResponse]
}
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 addservice.Service, logger log.Logger, duration metrics.Histogram, otTracer stdopentracing.Tracer, zipkinTracer *stdzipkin.Tracer) Set
New returns a Set that wraps the provided server, and wires in all of the expected endpoint middlewares via the various parameters.
type SumRequest ¶
type SumRequest struct {
A, B int
}
SumRequest collects the request parameters for the Sum method.
type SumResponse ¶
type SumResponse struct {
V int `json:"v"`
Err error `json:"-"` // should be intercepted by Failed/errorEncoder
}
SumResponse collects the response values for the Sum method.
