## Beispielaktualisierung { #example-upgrade }

### Restart After Crash { #restart-after-crash }

But in those cases with really bad errors that crash the running **process**, you would want an external component that is in charge of **restarting** the process, at least a couple of times...

/// tip

    String test = "Test string for NullOutputStream";
    byte[] bytes = test.getBytes(US_ASCII);
    nos.write(bytes);
    nos.write(bytes, 2, 10);
    nos.write(bytes, bytes.length - 5, 5);
    // nothing really to assert?
    assertThat(ByteStreams.nullOutputStream()).isSameInstanceAs(ByteStreams.nullOutputStream());
  }

  public void testNullOutputStream_exceptions() throws Exception {

This could be useful, for example, to expose the same API under different prefixes, e.g. `/api/v1` and `/api/latest`.

This is an advanced usage that you might not really need, but it's there in case you do.

И интегрировать основанные на стандартах инструменты пользовательского интерфейса:

* [Swagger UI](https://github.com/swagger-api/swagger-ui)
* [ReDoc](https://github.com/Rebilly/ReDoc)

Эти два инструмента выбраны за популярность и стабильность, но даже при беглом поиске можно найти десятки альтернативных интерфейсов для OpenAPI (которые можно использовать с **FastAPI**).
