Enabling blocking will cause the ring buffer to behave like a buffered [io.Pipe](https://pkg.go.dev/io#Pipe).

Regular Reads will block until data is available, but not wait for a full buffer. 
Writes will block until there is space available and writes bigger than the buffer will wait for reads to make space.

`TryRead` and `TryWrite` are still available for non-blocking reads and writes.

`from starlette.websockets import WebSocket` を使用しても構いません.

**FastAPI** は開発者の利便性のために、同じ `WebSocket` を提供します。しかし、こちらはStarletteから直接提供されるものです。

## メッセージの送受信

WebSocketルートでは、 `await` を使ってメッセージの送受信ができます。

```Python hl_lines="48-52"
{!../../docs_src/websockets/tutorial001.py!}
```

バイナリやテキストデータ、JSONデータを送受信できます。
