Function ErrorEncoder

http/encoding.go:262–272

ErrorEncoder returns an encoder that encodes errors returned by service methods. The default encoder checks whether the error is a goa ServiceError struct and if so uses the error temporary and timeout fields to infer a proper HTTP status code and marshals the error struct to the body using the prov

(encoder func(context.Context, http.ResponseWriter) Encoder, formatter func(ctx context.Context, err error) Statuser)

// encoded as a permanent internal server error. This behavior as well as the
// shape of the response can be overridden by providing a non-nil formatter.
func ErrorEncoder(encoder func(context.Context, http.ResponseWriter) Encoder, formatter func(ctx context.Context, err error) Statuser) func(context.Context, http.ResponseWriter, error) error {
	return func(ctx context.Context, w http.ResponseWriter, err error) error {
		enc := encoder(ctx, w)
		if formatter == nil {
			formatter = NewErrorResponse
		}
		resp := formatter(ctx, err)
		w.WriteHeader(resp.StatusCode())
		return enc.Encode(resp)
	}
}

// Decode implements the Decoder interface. It simply calls f(v).
func (f EncodingFunc) Decode(v any) error { return f(v) }
