Struct bevy::ecs::archetype::Edges

pub struct Edges { /* private fields */ }

Archetypes and bundles form a graph. Adding or removing a bundle moves an Entity to a new Archetype.

Edges caches the results of these moves. Each archetype caches the result of a structural alteration. This can be used to monitor the state of the archetype graph.

Note: This type only contains edges the World has already traversed. If any of functions return None, it doesn’t mean there is guaranteed not to be a result of adding or removing that bundle, but rather that operation that has moved an entity along that edge has not been performed yet.

Implementations

pub fn get_remove_bundle_intersection(
    &self,
    bundle_id: BundleId
) -> Option<Option<ArchetypeId>>
