/**
 * This class contains static utility methods that operate on or return objects of type {@link
 * Iterator}. Except as noted, each method has a corresponding {@link Iterable}-based method in the
 * {@link Iterables} class.
 *
 * <p><i>Performance notes:</i> Unless otherwise noted, all of the iterators produced in this class
 * are <i>lazy</i>, which means that they only advance the backing iteration when absolutely
 * necessary.

premières idées qui a inspiré "la recherche de" **FastAPI**.

   * Compares the two specified {@code byte} values. The sign of the value returned is the same as
   * that of {@code ((Byte) a).compareTo(b)}.

## `Header`のパラメータの宣言

次に、`Path`や`Query`、`Cookie`と同じ構造を用いてヘッダーのパラメータを宣言します。

最初の値がデフォルト値で、追加の検証パラメータや注釈パラメータをすべて渡すことができます。

```Python hl_lines="9"
{!../../docs_src/header_params/tutorial001.py!}
```

/// note | "技術詳細"

`Header`は`Path`や`Query`、`Cookie`の「姉妹」クラスです。また、同じ共通の`Param`クラスを継承しています。

しかし、`fastapi`から`Query`や`Path`、`Header`などをインポートする場合、それらは実際には特殊なクラスを返す関数であることを覚えておいてください。
