## 協程

**協程** 只是 `async def` 函式所回傳的非常特殊的事物名稱。Python 知道它是一個類似函式的東西，可以啟動它，並且在某個時刻它會結束，但它也可能在內部暫停 ⏸，只要遇到 `await`。

這種使用 `async` 和 `await` 的非同步程式碼功能通常被概括為「協程」。這與 Go 語言的主要特性「Goroutines」相似。

## 結論

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（通過 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

public final class okhttp3/coroutines/ExecuteAsyncKt {
	public static final fun executeAsync (Lokhttp3/Call;Lkotlin/coroutines/Continuation;)Ljava/lang/Object;

OkHttp Coroutines
=================

Support for Kotlin clients using coroutines.

```kotlin
val call = client.newCall(request)

call.executeAsync().use { response ->
  withContext(Dispatchers.IO) {
    println(response.body?.string())
  }
}
```

This is implemented using `suspendCancellableCoroutine`
but uses the standard Dispatcher in OkHttp. This means
that by default Kotlin's Dispatchers are not used.

<a href="#Length_and_capacity"><code>cap</code></a> and
<a href="#Length_and_capacity"><code>len</code></a>
by any number of goroutines without further synchronization.
Channels act as first-in-first-out queues.
For example, if one goroutine sends values on a channel
and a second goroutine receives them, the values are
received in the order sent.

- Add azure disk WriteAccelerator support ([#87945](https://github.com/kubernetes/kubernetes/pull/87945), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider and Storage]
- Add delays between goroutines for vm instance update ([#88094](https://github.com/kubernetes/kubernetes/pull/88094), [@aramase](https://github.com/aramase)) [SIG Cloud Provider]

- The `goroutines` metric is newly added in the scheduler. 

## Fazit

Sehen wir uns den gleichen Satz von oben noch mal an:

> Moderne Versionen von Python unterstützen **„asynchronen Code“** unter Verwendung sogenannter **„Coroutinen“** mithilfe der Syntax **`async`** und **`await`**.

			bucketCh <- b
		}
	}
	xioutil.SafeClose(bucketCh)

	bucketResults := make(chan dataUsageEntryInfo, len(disks))

	// Start async collector/saver.
	// This goroutine owns the cache.
	var saverWg sync.WaitGroup
	saverWg.Add(1)
	go func() {
		// Add jitter to the update time so multiple sets don't sync up.

## Version 5.0.0-alpha.14

_2024-04-17_

 *  Breaking: Move coroutines extensions to okhttp3.coroutines. Previously this artifact shared the
    `okhttp3` package name with our core module, which is incompatible with the Java Platform Module
    System.

 *  Fix in okhttp-coroutines: Publish a valid artifact. The coroutines JAR file in 5.0.0-alpha.13
    was corrupt and should not be used.
