`Header` es una clase "hermana" de `Path`, `Query` y `Cookie`. También hereda de la misma clase común `Param`.

[runtime.Pinner].

The _GoString_ type also may not be pinned with [runtime.Pinner].
Because it includes a Go pointer, the memory it points to is only pinned
for the duration of the call; _GoString_ values may not be retained by C
code.

A Go function called by C code may return a Go pointer to pinned memory
(which implies that it may not return a string, slice, channel, and so

FastAPI 0.110.0 より前では、`yield` を持つ依存関係を使い、その依存関係内で `except` によって例外を捕捉し、再度その例外を送出しなかった場合でも、その例外は自動的に送出（フォワード）され、任意の例外ハンドラまたは内部サーバエラーハンドラに渡されていました。

これは、ハンドラのないフォワードされた例外（内部サーバエラー）による未処理のメモリ消費を修正し、通常の Python コードの挙動と一貫性を持たせるため、バージョン 0.110.0 で変更されました。
