Der einzige Unterschied besteht darin, dass die `HTTPException` von **FastAPI** beliebige JSON-konvertierbare Daten für das `detail`-Feld akzeptiert, während die `HTTPException` von Starlette nur Strings dafür akzeptiert.

Sie können also weiterhin die `HTTPException` von **FastAPI** wie üblich in Ihrem Code auslösen.

Eine weitere wichtige Funktion, benötigt von APIs, ist die Datenvalidierung, welche sicherstellt, dass die Daten unter gegebenen Umständen gültig sind. Zum Beispiel, dass ein Feld ein `int` ist und kein zufälliger String. Das ist besonders nützlich für hereinkommende Daten.

Ohne ein Datenvalidierungssystem müssten Sie alle Prüfungen manuell im Code durchführen.

      // TODO(b/145386688): This access should be guarded by 'this.segment', which is not currently
      // held
      chain = segment.newEntry(key, cache.hash(key), chain);
      if (i == 0) {
        head = chain;
      }
    }
  }

#### Http2Connection

This lock guards internal state of each connection. This lock is never held for blocking operations. That means that we acquire the lock, read or write a few fields and release the lock. No I/O and no application-layer callbacks.
