Struct re_viewer_context::ViewContext

pub struct ViewContext<'a> {
    pub viewer_ctx: &'a ViewerContext<'a>,
    pub view_id: SpaceViewId,
    pub view_state: &'a dyn SpaceViewState,
    pub defaults_path: &'a EntityPath,
    pub visualizer_collection: Arc<VisualizerCollection>,
}

The context associated with a view.

This combines our crate::ViewerContext with crate::SpaceViewState 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: SpaceViewId

view_state: &'a dyn SpaceViewState

defaults_path: &'a EntityPath

visualizer_collection: Arc<VisualizerCollection>
