etected.
        debug: whether to print information about all filesystem changes in rust to stdout.
        raise_interrupt: whether to re-raise `KeyboardInterrupt`s, or suppress the error and just stop iterating.
        force_polling: See [Force polling](#force-polling) above.
        poll_delay_ms: delay between polling for changes, only used if `force_polling=True`.
        recursive: if `True`, watch for changes in sub-directories recursively, otherwise watch only for changes in the
            top-level directory, default is `True`.
        ignore_permission_denied: if `True`, will ignore permission denied errors, otherwise will raise them by default.
            Setting the `WATCHFILES_IGNORE_PERMISSION_DENIED` environment variable will set this value too.

    Yields:
        The generator yields sets of [`FileChange`][watchfiles.main.FileChange]s.

    ```py title="Example of watch usage"
    from watchfiles import watch

    for changes in watch('./first/dir', './second/dir', raise_interrupt=False):
        print(changes)
