* If a PR doesn't explain what it does or why, if it seems like it could be useful, ask for more information. Otherwise, feel free to close it.

* If a PR seems to be spam, meaningless, only to change statistics (to appear as "contributor") or similar, you can simply mark it as `invalid`, and it will be automatically closed.

    * 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()

    init {
      val source = snapshot.getSource(ENTRY_BODY)
      bodySource =
        object : ForwardingSource(source) {
          @Throws(IOException::class)
          override fun close() {
            snapshot.close()
            super.close()
          }
        }.buffer()
    }

    override fun contentType(): MediaType? = contentType?.toMediaTypeOrNull()

    }

     * with it.

When a WebSocket connection is closed, the `await websocket.receive_text()` will raise a `WebSocketDisconnect` exception, which you can then catch and handle like in this example.
