If a package has any .s files, then <code>go build</code> will direct

which the .s files can then <code>#include</code>.
The file contains symbolic <code>#define</code> constants for the
offsets of Go struct fields, the sizes of Go struct types, and most

## 特殊な型とバリデーション

`str`や`int`、`float`のような通常の単数型の他にも、`str`を継承したより複雑な単数型を使うこともできます。

すべてのオプションをみるには、<a href="https://docs.pydantic.dev/latest/concepts/types/" class="external-link" target="_blank">Pydanticのエキゾチック な型</a>のドキュメントを確認してください。次の章でいくつかの例をみることができます。

例えば、`Image`モデルのように`url`フィールドがある場合、`str`の代わりにPydanticの`HttpUrl`を指定することができます:

```Python hl_lines="4 10"

	}
	req.Header.Set("x-amz-content-sha256", hashedPayload)

	// Add Content-Length
	req.ContentLength = contentLength

	return req, nil
}

// Various signature types we are supporting, currently
// two main signature types.
type signerType int

const (
	signerV2 signerType = iota
	signerV4
)
