    Call the given function with the given arguments in a worker thread.

    If the ``cancellable`` option is enabled and the task waiting for its completion is
    cancelled, the thread will still run its course but its return value (or any raised
    exception) will be ignored.

    :param func: a callable
    :param args: positional arguments for the callable
    :param abandon_on_cancel: ``True`` to abandon the thread (leaving it to run
        unchecked on own) if the host task is cancelled, ``False`` to ignore
        cancellations in the host task until the operation has completed in the worker
        thread
    :param cancellable: deprecated alias of ``abandon_on_cancel``; will override
        ``abandon_on_cancel`` if both parameters are passed
    :param limiter: capacity limiter to use to limit the total amount of threads running
        (if omitted, the default limiter is used)
    :return: an awaitable that yields the return value of the function.

    NzThe `cancellable=` keyword argument to `anyio.to_thread.run_sync` is deprecated since AnyIO 4.1.0; use `abandon_on_cancel=` instead   )

    Return the capacity limiter that is used by default to limit the number of
    concurrent threads.

    :return: a capacity limiter object
