}

The EntityStore trait abstracts access to entity data as required by queries for both World and SubWorld

Returns the world’s unique ID.

fn entry_ref(&self, entity: Entity) -> Result<EntryRef<'_>, EntityAccessError>

Returns an entity entry which can be used to access entity metadata and components.

fn entry_mut(
    &mut self,
    entity: Entity
) -> Result<EntryMut<'_>, EntityAccessError>

Returns a mutable entity entry which can be used to access entity metadata and components.

fn get_component_storage<V: for<'b> View<'b>>(
    &self
) -> Result<StorageAccessor<'_>, EntityAccessError>
