# Nebenläufigkeit und async / await

Details zur `async def`-Syntax für *Pfadoperation-Funktionen* und Hintergrundinformationen zu asynchronem Code, Nebenläufigkeit und Parallelität.

## In Eile?

<abbr title="too long; didn't read – Zu lang; nicht gelesen"><strong>TL;DR:</strong></abbr>

Wenn Sie Bibliotheken von Dritten verwenden, die mit `await` aufgerufen werden müssen, wie zum Beispiel:

```Python
results = await some_library()
```

# Download CUDA/CUDNN redistributions to preserve the repositories cache between
# CPU and GPU builds.
# TODO(ybaturina): Uncomment when RBE is ready to support this.
# build:rbe_linux_cpu --repo_env USE_CUDA_REDISTRIBUTIONS=1
# build:rbe_linux_cpu --config=cuda_version

# Deprecated RBE config with non-hermetic toolchains.

# 並行與 async / await

## 趕時間嗎?

<abbr title="too long; didn't read（文長慎入）"><strong>TL;DR:</strong></abbr>

如果你正在使用要求你以 `await` 語法呼叫的第三方函式庫，例如：

```Python
results = await some_library()
```

然後，使用 `async def` 宣告你的*路徑操作函式*：


```Python hl_lines="2"
@app.get('/')
async def read_results():
    results = await some_library()

            final byte[] bomBytes = new byte[UTF8_BOM_SIZE];
            bis.mark(UTF8_BOM_SIZE);
            final int size = bis.read(bomBytes);
            if (size < 3 || !isUtf8BomBytes(bomBytes)) {
                bis.reset();
            }
            final InputSource is = new InputSource(bis);
            if (responseData.getCharSet() != null) {
