### 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.

    // This sentence just isn't base64() encoded.
    assertFailsToDecode(base64(), "let's not talk of love or chains!");
    // A 4n+1 length string is never legal base64().
    assertFailsToDecode(base64(), "12345", "Invalid input length 5");
    // These have a combination of invalid length, unrecognized characters and wrong padding.
