[−][src]Struct oxygengine_core::ecs::storage::RestrictedStorage
Similar to a MaskedStorage
and a Storage
combined, but restricts usage
to only getting and modifying the components. That means it's not possible to
modify the inner bitset so the iteration cannot be invalidated. In other words,
no insertion or removal is allowed.
Example Usage:
struct SomeComp(u32); impl Component for SomeComp { type Storage = VecStorage<Self>; } struct RestrictedSystem; impl<'a> System<'a> for RestrictedSystem { type SystemData = ( Entities<'a>, WriteStorage<'a, SomeComp>, ); fn run(&mut self, (entities, mut some_comps): Self::SystemData) { for (entity, mut comps) in ( &entities, &mut some_comps.restrict_mut() ).join() { // Check if the reference is fine to mutate. if comps.get_unchecked().0 < 5 { // Get a mutable reference now. let mut mutable = comps.get_mut_unchecked(); mutable.0 += 1; } } } }
