Golang generic retry

retry.go

func Retry[T any](effector func(ctx context.Context) (T, error), retries int, delay time.Duration) func(context.Context) (*T, error) {
	return func(ctx context.Context) (*T, error) {
		for r := 0; ; r++ {
			response, err := effector(ctx)
			if err == nil || r >= retries {
				// Return when there is no error or the maximum amount
				// of retries is reached.
				return &response, err
			}

			log.Println("Function call failed, retrying in", delay)

			select {
			case <-time.After(delay):
			case <-ctx.Done():
				return nil, ctx.Err()
			}
		}
	}
}
