When a client disconnects, a `WebSocketDisconnect` exception is raised, you can catch it.

You can import it directly form `fastapi`:

```python
from fastapi import WebSocketDisconnect
```

::: fastapi.WebSocketDisconnect

## WebSockets - additional classes

    *   Improve the informativeness of error messages raised by Keras
        `Layer.__call__()`, by adding the full list of argument values passed to
        the layer in every exception.

*   Introduce the `tf.compat.v1.keras.utils.track_tf1_style_variables`
    decorator, which enables using large classes of tf1-style variable_scope,
    `get_variable`, and `compat.v1.layer`-based components from within TF2

    Note over client,operation: Can raise HTTPException and can change the response

The return parameters of the function are passed by value
