1. type SettingsBindGetMapping_WithClosures = GValue -> GVariant -> Ptr () -> IO Bool

   gi-gio	GI.Gio.Callbacks

   The type for the function that is used to convert from Settings to an object property. The value is already initialized to hold values of the appropriate type.

2. type SettingsBindSetMapping = GValue -> VariantType -> IO Maybe GVariant

   gi-gio	GI.Gio.Callbacks

   The type for the function that is used to convert an object property value to a GVariant for storing it in Settings.

3. type SettingsBindSetMapping_WithClosures = GValue -> VariantType -> Ptr () -> IO Maybe GVariant

   gi-gio	GI.Gio.Callbacks

   The type for the function that is used to convert an object property value to a GVariant for storing it in Settings.

4. type SettingsGetMapping = Maybe GVariant -> IO (Bool, Ptr ())

   gi-gio	GI.Gio.Callbacks

   The type of the function that is used to convert from a value stored in a Settings to a value that is useful to the application. If the value is successfully mapped, the result should be stored at result and True returned. If mapping fails (for example, if value is not in the right format) then False should be returned. If value is Nothing then it means that the mapping function is being given a "last chance" to successfully return a valid value. True must be returned in this case.

5. type SettingsGetMapping_WithClosures = Maybe GVariant -> Ptr () -> IO (Bool, Ptr ())

   gi-gio	GI.Gio.Callbacks

   The type of the function that is used to convert from a value stored in a Settings to a value that is useful to the application. If the value is successfully mapped, the result should be stored at result and True returned. If mapping fails (for example, if value is not in the right format) then False should be returned. If value is Nothing then it means that the mapping function is being given a "last chance" to successfully return a valid value. True must be returned in this case.

6. drop_closures_SettingsBindGetMapping :: SettingsBindGetMapping -> SettingsBindGetMapping_WithClosures

   gi-gio	GI.Gio.Callbacks

   A simple wrapper that ignores the closure arguments.

7. drop_closures_SettingsBindSetMapping :: SettingsBindSetMapping -> SettingsBindSetMapping_WithClosures

   gi-gio	GI.Gio.Callbacks

   A simple wrapper that ignores the closure arguments.

8. drop_closures_SettingsGetMapping :: SettingsGetMapping -> SettingsGetMapping_WithClosures

   gi-gio	GI.Gio.Callbacks

   A simple wrapper that ignores the closure arguments.

9. dynamic_SettingsBindGetMapping :: (HasCallStack, MonadIO m) => FunPtr C_SettingsBindGetMapping -> GValue -> GVariant -> Ptr () -> m Bool

   gi-gio	GI.Gio.Callbacks

   Given a pointer to a foreign C function, wrap it into a function callable from Haskell.

10. dynamic_SettingsBindSetMapping :: (HasCallStack, MonadIO m) => FunPtr C_SettingsBindSetMapping -> GValue -> VariantType -> Ptr () -> m (Maybe GVariant)

    gi-gio	GI.Gio.Callbacks

    Given a pointer to a foreign C function, wrap it into a function callable from Haskell.
