### `StreamingResponse`

Recebe uma gerador assíncrono ou um gerador/iterador comum e retorna o corpo da requisição continuamente (stream).

No Python 3.10 também existe uma **nova sintaxe** onde você pode colocar os possívels tipos separados por uma <abbr title='também chamado de "bitwise ou operador", mas o significado é irrelevante aqui'>barra vertical (`|`)</abbr>.

O `@app.get("/")` diz ao **FastAPI** que a função logo abaixo é responsável por tratar as requisições que vão para:

* a rota `/`
* usando o  <abbr title="o método HTTP GET">operador <code>get</code></abbr>

Essa sintaxe `@alguma_coisa` em Python é chamada de "decorador".

Você o coloca em cima de uma função. Como um chapéu decorativo (acho que é daí que vem o termo).
