    * JSON objeleri (`dict`).
    * JSON array (`list`) item type'ı belirtirken.
    * String (`str`) parametresi, minimum ve maksimum uzunluk gibi sınırlandırmalar yaparken.
    * Numaralar (`int`, `float`) maksimum ve minimum gibi sınırlandırmalar yaparken.

* Bunlar gibi en egzotik typelarla bile doğrulama yapabiliyorsunuz.:
    * URL.
    * Email.
    * UUID.
    * ...ve diğerleri.

By declaring types for your variables, editors and tools can give you better support.

This is just a **quick tutorial / refresher** about Python type hints. It covers only the minimum necessary to use them with **FastAPI**... which is actually very little.

**FastAPI** is all based on these type hints, they give it many advantages and benefits.

Diese Middleware verarbeitet sowohl Standard- als auch Streaming-Responses.

Die folgenden Argumente werden unterstützt:

* `minimum_size` – Antworten, die kleiner als diese Mindestgröße in Bytes sind, nicht per GZip komprimieren. Der Defaultwert ist `500`.
