/// [`DevicePad`][crate::DevicePad] is an interface implemented by devices of type
/// [`InputSource::TabletPad`][crate::InputSource::TabletPad], it allows querying the features provided
/// by the pad device.
///
/// Tablet pads may contain one or more groups, each containing a subset
/// of the buttons/rings/strips available. [`DevicePadExt::n_groups()`][crate::prelude::DevicePadExt::n_groups()]
/// can be used to obtain the number of groups, [`DevicePadExt::n_features()`][crate::prelude::DevicePadExt::n_features()]
/// and [`DevicePadExt::feature_group()`][crate::prelude::DevicePadExt::feature_group()] can be combined to find out the
/// number of buttons/rings/strips the device has, and how are they grouped.
///
/// Each of those groups have different modes, which may be used to map
/// each individual pad feature to multiple actions. Only one mode is
/// effective (current) for each given group, different groups may have
/// different current modes. The number of available modes in a group can
/// be found out through [`DevicePadExt::group_n_modes()`][crate::prelude::DevicePadExt::group_n_modes()], and the current
/// mode for a given group will be notified through the [`EventPadGroupMode`][crate::EventPadGroupMode]
