Mais si vous décidez d'apprendre à les utiliser, sachez qu'ensuite vous pouvez les utiliser directement dans **FastAPI**.

## Valeurs par défaut

De la même façon que vous pouvez passer `None` comme premier argument pour l'utiliser comme valeur par défaut, vous pouvez passer d'autres valeurs.

Disons que vous déclarez le paramètre `q` comme ayant une longueur minimale de `3`, et une valeur par défaut étant `"fixedquery"` :

	case int64:
		return x, nil
	case string:
		// Parse as number, truncate floating point if
		// needed.
		// String might contain trimming spaces, which
		// needs to be trimmed.
		res, ok := strToInt(strings.TrimSpace(x))
		if !ok {
			return 0, errCastFailure("could not parse as int")
		}
		return res, nil
	case []byte:
		// Parse as number, truncate floating point if
		// needed.

	}

	log.Debugf("istio-cni: Config is: %+v", conf)
	// Parse previous result. Remove this if your plugin is not chained.
	if conf.RawPrevResult != nil {
		resultBytes, err := json.Marshal(conf.RawPrevResult)
		if err != nil {

	}

	// There are two possibilities:
	// - We use a KMS -> There must be non-empty key ID and a KMS data key.
	// - We use a K/V -> There must be no key ID and no KMS data key.
	// Otherwise, the caller has passed an invalid argument combination.
	if keyID == "" && len(kmsKey) != 0 {
		logger.CriticalIf(context.Background(), errors.New("The key ID must not be empty if a KMS data key is present"))
	}
