  <description summary="configure libinput devices">
    This protocol exposes libinput device configuration APIs. The libinput
    documentation should be referred to for detailed information on libinput's
    behavior.

    Note that the compositor will not be able to expose libinput devices through
    this protocol when it does not have access to the hardware, for example when
    running nested in another Wayland compositor or X11 session.

    This protocol is designed so that (hopefully) any backwards compatible
    change to libinput's API can be matched with a backwards compatible change
    to this protocol.

    Note: the libinput API uses floating point types (float and double in C)
    which are not (yet?) natively supported by the Wayland protocol. However,
    the Wayland protocol does support sending arbitrary bytes through the array
    argument type. This protocol uses e.g. type="array" summary="double" to
    indicate a native-endian IEEE-754 64-bit double value.

    The key words "must", "must not", "required", "shall", "shall not",
    "should", "should not", "recommended", "may", and "optional" in this
    document are to be interpreted as described in IETF RFC 2119.

        The Wayland protocol is asynchronous, which means the server may send
        further events until the stop request is processed. The client must wait

        It is a protocol error to make this request before the finished event

        If a client wishes to destroy this object it should send a
        river_libinput_config_v1.stop request and wait for a
        river_libinput_config_v1.finished event. Once the finished event is
