Expand description

Updates that must be reacted by an app owner.

This type is public only for testing, it is the return type for test methods of WINDOW.

Fields§

§events: Vec<EventUpdate>

Events to notify.

When this is not empty update is true.

§update: bool

Update requested.

When this is true, update_widgets may contain widgets, if not then only app extensions must update.

§info: bool

Info rebuild requested.

When this is true, info_widgets may contain widgets, if not then only app extensions must update.

§layout: bool

Layout requested.

When this is true, layout_widgets may contain widgets, if not then only app extensions must update.

§render: bool

Render requested.

When this is true, render_widgets or render_update_widgets may contain widgets, if not then only app extensions must update.

§update_widgets: WidgetUpdates

Update targets.

When this is not empty update is true.

§info_widgets: InfoUpdates

Info rebuild targets.

When this is not empty info is true.

§layout_widgets: LayoutUpdates

Layout targets.

When this is not empty layout is true.

§render_widgets: RenderUpdates

Full render targets.

When this is not empty render is true.

§render_update_widgets: RenderUpdates

Render update targets.

When this is not empty render is true.
