# 将 ReadableStream 转换为 ArrayBuffer

Bun 提供了若干便捷函数，可将 [`ReadableStream`](https://developer.mozilla.org/en-US/docs/Web/API/ReadableStream) 的内容读取成不同格式。

```ts theme={"theme":{"light":"github-light","dark":"dracula"}}
const stream = new ReadableStream();
const buf = await Bun.readableStreamToArrayBuffer(stream);
```
