CustomFragmentRule

@IviExperimental(reasons = [])
interface CustomFragmentRule<P : AnyPanel>

A rule to replace the normal Fragment of a Panel of type P with a custom fragment. This makes it possible to not only change the layout of a panel, but also to display additional information and/or add custom interaction.

The rules are used by a PanelContainer. The rules are part of the PanelContainerContext, and can be configured in PanelContainer.ttiviPanelContainerContext.
