### Other utility functions

Any other utility function that you call directly can be created with normal `def` or `async def` and FastAPI won't affect the way you call it.

This is in contrast to the functions that FastAPI calls for you: *path operation functions* and dependencies.

* A API checa aquele `username` e `senha`, e responde com um "token" (nós não implementamos nada disso ainda).
	* Um "token" é apenas uma string com algum conteúdo que nós podemos utilizar mais tarde para verificar o usuário.
	* Normalmente, um token é definido para expirar depois de um tempo.
		* Então, o usuário terá que se logar de novo depois de um tempo.

/// note

**FastAPI** saura que `q` est optionnel grâce au `=None`.

Le `Optional` dans `Optional[str]` n'est pas utilisé par **FastAPI** (**FastAPI** n'en utilisera que la partie `str`), mais il servira tout de même à votre éditeur de texte pour détecter des erreurs dans votre code.

## Utilização de recursos

Seu(s) servidor(es) é(são) um **recurso** que você pode consumir ou **utilizar**, com seus programas, o tempo de computação nas CPUs e a memória RAM disponível.

Quanto dos recursos do sistema você quer consumir/utilizar? Pode ser fácil pensar "não muito", mas, na realidade, você provavelmente vai querer consumir **o máximo possível sem travar**.
