    * E.g., `await myfile.seek(0)` would go to the start of the file.
    * This is especially useful if you run `await myfile.read()` once and then need to read the contents again.
* `close()`: Closes the file.

As all these methods are `async` methods, you need to "await" them.

For example, inside of an `async` *path operation function* you can get the contents with:

```Python
contents = await myfile.read()

        this.dataLength = len;
        this.digest = null; /*
                             * otherwise recycled commands

                             * closes in between
                             */

 *  Fix: Improve recovery from failed routes.
 *  Fix: Accommodate tunneling proxies that close the connection after an auth
    challenge.
 *  Fix: Use the proxy authenticator when authenticating HTTP proxies. This
    regression was introduced in OkHttp 3.0.
 *  Fix: Fail fast if network interceptors transform the response body such that
    closing it doesn't also close the underlying stream. We had a bug where
