### Outras funções de utilidade

Qualquer outra função de utilidade que você chame diretamente pode ser criada com `def` normal ou `async def` e o FastAPI não irá afetar o modo como você a chama.

Isso está em contraste às funções que o FastAPI chama para você: *funções de operação de rota* e dependências.
