Struct rerun::external::re_viewer_context::ViewContext

pub struct ViewContext<'a> {
    pub viewer_ctx: &'a ViewerContext<'a>,
    pub view_id: BlueprintId<ViewIdRegistry>,
    pub view_state: &'a (dyn ViewState + 'static),
    pub visualizer_collection: Arc<VisualizerCollection>,
    pub query_result: &'a DataQueryResult,
}

The context associated with a view.

This combines our crate::ViewerContext with crate::ViewState and other view-specific information. This is used as the interface for execution of view systems and selection panel UI elements that happen within the context of a view to simplify plumbing of the necessary information to resolve a query with possible overrides and fallback values.

Fields

viewer_ctx: &'a ViewerContext<'a>

view_id: BlueprintId<ViewIdRegistry>
