## Dépendances facultatives

Utilisées par Pydantic:

Utilisées par Starlette :

        assertEquals(data.hashCode(), blob.hashCode(), "hashCode should equal the array's hashCode");
    }

	if t, ok := config.Tiers[tierName]; ok {

	}
	return madmin.Unsupported, false
}

// Add adds tier to config if it passes all validations.
func (config *TierConfigMgr) Add(ctx context.Context, tier madmin.TierConfig, ignoreInUse bool) error {

	defer config.Unlock()

	// check if tier name is in all caps
	tierName := tier.Name

	}

	return sys.store.UpdateUserSecretKey(ctx, accessKey, secretKey)
}

// purgeExpiredCredentialsForExternalSSO - validates if local credentials are still valid
// by checking remote IDP if the relevant users are still active and present.

When you install FastAPI with `pip install "fastapi[standard]"` it comes with the `standard` group of optional dependencies:

Used by Pydantic:

* <a href="https://github.com/JoshData/python-email-validator" target="_blank"><code>email-validator</code></a> - for email validation.

Used by Starlette:

* <a href="https://www.python-httpx.org" target="_blank"><code>httpx</code></a> - Required if you want to use the `TestClient`.

You can use all the same validation features and tools you use for Pydantic models, like different data types and additional validations with `Field()`.
