* **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:

	sa := local.NewSourceAnalyzer(analysis.Combine("webhook", &webhook.Analyzer{}), "", resource.Namespace(istioNamespace), nil)
	if err := sa.AddReaderKubeSource([]local.ReaderSource{{Name: "", Reader: strings.NewReader(wh)}}); err != nil {
		return err
	}
	k, err := kube.NewClient(kube.NewClientConfigForRestConfig(config), "")
	if err != nil {
		return err
	}

```

Read the new docs: [Header Parameter Models](https://fastapi.tiangolo.com/tutorial/header-param-models/).

#### `Cookie` Parameter Models

Use Pydantic models for `Cookie` parameters:

```python

&.show { opacity: $modal-backdrop-opacity; }\n}\n\n// Modal header\n// Top section of the modal w/ title and dismiss\n.modal-header {\n  display: flex;\n  align-items: flex-start; // so the close btn always stays on the upper right corner\n  justify-content: space-between; // Put modal header elements (title and dismiss) on opposite ends\n  padding: $modal-header-padding;\n  border-bottom: $modal-header-border-width solid $modal-header-border-color;\n  @include border-top-radius($modal-content-i...

	}
}

type repeatedByte struct {
	off int64
	b   byte
	n   int64
}

// rleBuffer is a run-length-encoded byte buffer.
// It's an io.Writer (like a bytes.Buffer) and also an io.ReaderAt,
// allowing random-access reads.
type rleBuffer struct {
	buf []repeatedByte
}

func (r *rleBuffer) Size() int64 {
	if len(r.buf) == 0 {
		return 0
	}
	last := &r.buf[len(r.buf)-1]
	return last.off + last.n

* **Sự hỗ trợ từ các trình soạn thảo**.
* **Kiểm tra kiểu dữ liệu (type checking)**.

...và **FastAPI** sử dụng các khia báo để:

* **Định nghĩa các yêu cầu**: từ tham số đường dẫn của request, tham số query, headers, bodies, các phụ thuộc (dependencies),...
* **Chuyển dổi dữ liệu*: từ request sang kiểu dữ liệu được yêu cầu.
* **Kiểm tra tính đúng đắn của dữ liệu**: tới từ mỗi request:

build:windows --copt=/Zc:__cplusplus
build:windows --host_copt=/Zc:__cplusplus

# Tensorflow uses M_* math constants that only get defined by MSVC headers if
# _USE_MATH_DEFINES is defined.
build:windows --copt=/D_USE_MATH_DEFINES
build:windows --host_copt=/D_USE_MATH_DEFINES

# Windows has a relatively short command line limit, which TF has begun to hit.
