## Opinions

"_[...] J'utilise beaucoup **FastAPI** ces derniers temps. [...] Je prévois de l'utiliser dans mon équipe pour tous les **services de ML chez Microsoft**. Certains d'entre eux seront intégrés dans le coeur de **Windows** et dans certains produits **Office**._"

L'utilisation d'`async` et `await` est relativement nouvelle dans ce langage.

Mais cela rend la programmation asynchrone bien plus simple.

Cette même syntaxe (ou presque) était aussi incluse dans les versions modernes de Javascript (dans les versions navigateur et NodeJS).

Mais avant ça, gérer du code asynchrone était bien plus complexe et difficile.

## Watch le dépôt GitHub pour les releases

Vous pouvez "watch" FastAPI dans GitHub (en cliquant sur le bouton "watch" en haut à droite) : <a href="https://github.com/fastapi/fastapi" class="external-link" target="_blank">https://github.com/fastapi/fastapi</a>. 👀

Vous pouvez y sélectionner "Releases only".

type fanOutOptions struct {

	KeyID    string
	Key      []byte
	KmsCtx   kms.Context
	Checksum *hash.Checksum
	MD5Hex   string
}

// fanOutPutObject takes an input source reader and fans out multiple PUT operations
// based on the incoming fan-out request, a context cancellation by the caller
// would ensure all fan-out operations are canceled.

And then they can try again knowing that it's probably something more similar to `stanleyjobsox` than to `johndoe`.

#### A "professional" attack { #a-professional-attack }

Of course, the attackers would not try all this by hand, they would write a program to do it, possibly with thousands or millions of tests per second. And they would get just one extra correct letter at a time.

## Pydantic { #pydantic }

All the data validation is performed under the hood by <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a>, so you get all the benefits from it. And you know you are in good hands.

You can use the same type declarations with `str`, `float`, `bool` and many other complex data types.

Several of these are explored in the next chapters of the tutorial.

   * name, even if their bounds differ.

   * <p>While resolving a type variable from a {@code var -> type} map, we don't care whether the
