**FastAPI**, Python tip belirteçlerini kullanarak parametre belirlemede ve API'ı otomatık tanımlayan bir şema üretmede de Hug'a esinlendi.

**FastAPI**'ın header ve çerez tanımlamak için fonksiyonlarda `response` parametresini belirtmesinde de Hug'dan ilham alındı.

* **Editor ondersteuning**.
* **Type checks**.

...en **FastAPI** gebruikt dezelfde declaraties om:

* **Vereisten te definïeren **: van request pad parameters, query parameters, headers, bodies, dependencies, enz.
* **Data te converteren**: van de request naar het vereiste type.
* **Data te valideren**: afkomstig van elke request:

// has been used.
// The returned reader contains the payload.
func waitForHTTPResponse(respBody io.Reader) (io.Reader, error) {
	reader := bufio.NewReader(respBody)
	for {
		b, err := reader.ReadByte()
		if err != nil {
			return nil, err
		}
		// Check if we have a response ready or a filler byte.
		switch b {
		case 0:
			return reader, nil
		case 1:
			errorText, err := io.ReadAll(reader)

			newSetCounts[ss] = struct{}{}
		}
	}

	setCounts = []uint64{}
	for setCount := range newSetCounts {
		setCounts = append(setCounts, setCount)
	}

	// Not necessarily needed but it ensures to the readers
	// eyes that we prefer a sorted setCount slice for the
	// subsequent function to figure out the right common
	// divisor, it avoids loops.
	sort.Slice(setCounts, func(i, j int) bool {

		return
	}

	// Ensure body content type is opaque to ensure that request body has not
	// been interpreted as form data.
	contentType := r.Header.Get("Content-Type")
	if contentType != "application/octet-stream" {
		writeErrorResponseJSON(ctx, w, errorCodes.ToAPIErr(ErrBadRequest), r.URL)
		return
	}

	// Validate operation

* **Editor support**.
* **Type checks**.

...and **FastAPI** uses the same declarations to:

* **Define requirements**: from request path parameters, query parameters, headers, bodies, dependencies, etc.
* **Convert data**: from the request to the required type.
* **Validate data**: coming from each request:
    * Generating **automatic errors** returned to the client when the data is invalid.

    /** The key of the message: <ul class="has-error"> */
    public static final String ERRORS_HEADER = "{errors.header}";

    public static final String ERRORS_FOOTER = "{errors.footer}";

				// If versioned we have no conflicts.
				fi.SetInlineData()

			// For overwritten objects without header we might have a
			// conflict with data written later. Check the data path

In diese Exception fügen wir (falls vorhanden) die erforderlichen Scopes als durch Leerzeichen getrennten String ein (unter Verwendung von `scope_str`). Wir fügen diesen String mit den Scopes in den Header `WWW-Authenticate` ein (das ist Teil der Spezifikation).
