      Middleware describes a service specific middleware

      func InstrumentingMiddleware

      func InstrumentingMiddleware(counters Counters) Middleware

        InstrumentingMiddleware returns a service middleware that instruments the number of users created over the lifetime of the service.

        func LoggingMiddleware

        func LoggingMiddleware(logger *zap.Logger) Middleware

          type Service

          type Service interface {
          	// CreateUser effectively creates/adds a user object to the backend data store
          	// if it doesm't already exist.
          	CreateUser(ctx context.Context, user user_service.UserORM) (err error)
          	// GetUserById queries the backend datastore for user objects based on a
          	// passed in user id parameter.
          	GetUserById(ctx context.Context, id string) (user user_service.UserORM, err error)
          	// GetUserByEmail queries the backend datastore for user objects based on a
          	// passed in user email parameter.
          	GetUserByEmail(ctx context.Context, email string) (user user_service.UserORM, err error)
          	// GetUserByUsername queries the backend datastore for user objects based on a
          	// passed in user username parameter.
          	GetUserByUsername(ctx context.Context, username string) (user user_service.UserORM, err error)
