2025'in sonunda yayınlanan bir [FastAPI mini belgeseli](https://www.youtube.com/watch?v=mpR8ngthqiE) var, online olarak izleyebilirsiniz:

	}

	for i, c := range cases {
		var err error
		var record sql.Record
		var result bytes.Buffer

		r, _ := NewReader(io.NopCloser(strings.NewReader(c.content)), &ReaderArgs{
			FileHeaderInfo:             none,
			RecordDelimiter:            c.recordDelimiter,

Eso debería tener más sentido ahora. ✨

Todo eso es lo que impulsa FastAPI (a través de Starlette) y lo que hace que tenga un rendimiento tan impresionante.

## Detalles Muy Técnicos { #very-technical-details }

Probablemente puedas saltarte esto.

Estos son detalles muy técnicos de cómo **FastAPI** funciona en su interior.

    for (i in 1015..2999) {
      data.write(("8802" + format("%04X", i)).decodeHex()) // Close with code 'i'
    }

## 結論 { #conclusion }

讓我們再次回顧之前的句子：

> 現代版本的 Python 支持使用 **"協程"** 的 **`async` 和 `await`** 語法來寫 **"非同步程式碼"**。

現在應該能明白其含意了。✨

這些就是驅動 FastAPI（透過 Starlette）運作的原理，也讓它擁有如此驚人的效能。

## 非常技術性的細節 { #very-technical-details }

/// warning

你大概可以跳過這段。

這裡是有關 FastAPI 內部技術細節。

如果你有相當多的技術背景（例如協程、執行緒、阻塞等），並且對 FastAPI 如何處理 `async def` 與常規 `def` 感到好奇，請繼續閱讀。
