- আরো অতিরিক্ত বৈশিষ্ট্য (স্টারলেটকে ধন্যবাদ) হিসাবে:
  - **WebSockets**
  - **GraphQL**
  - HTTPX এবং `pytest` ভিত্তিক অত্যন্ত সহজ পরীক্ষা
  - **CORS**
  - **Cookie Sessions**
  - ...এবং আরো।

## কর্মক্ষমতা

* Diğer ekstra özellikler (Starlette sayesinde):
    * **WebSocketler**
    * HTTPX ve `pytest` sayesinde aşırı kolay testler.
    * **CORS**
    * **Cookie Sessions**
    * ...ve daha fazlası.

## Performans

	lock    mutex // protects the following fields
	closing bool
	rrun    bool      // whether rt is running
	wrun    bool      // whether wt is running
	user    uint32    // user settable cookie
	rseq    uintptr   // protects from stale read timers
	rt      timer     // read deadline timer
	rd      int64     // read deadline (a nanotime in the future, -1 when expired)

!!! tip

    Here we are using `Query()` because this is a **query parameter**. Later we will see others like `Path()`, `Body()`, `Header()`, and `Cookie()`, that also accept the same arguments as `Query()`.

FastAPI will now:

* **Validate** the data making sure that the max length is 50 characters
* Show a **clear error** for the client when the data is not valid

    this.sslSocketFactory = sslSocketFactory
  }

  /**
   * Configure the server to not perform SSL authentication of the client. This leaves
   * authentication to another layer such as in an HTTP cookie or header. This is the default and
   * most common configuration.
   */
  fun noClientAuth() {
    this.clientAuth = CLIENT_AUTH_NONE
  }

    素晴らしい性能を得るための方法を見つけた点。

    Hug (HugはFalconをベースにしています) と一緒に、**FastAPI**が`response`引数を関数に持つことにインスピレーションを与えました。

    **FastAPI**では任意ですが、ヘッダーやCookieやステータスコードを設定するために利用されています。

**FastAPI**を構築する最初の段階でMoltenを発見しました。そして、それは非常に似たようなアイデアを持っています。
