pub struct WithRelated<I>(pub I);Expand description
A SpawnableList that links already spawned entities to the root entity via relations of type I.
This is useful if the entity has already been spawned earlier or if you spawn multiple relationships link to the same entity at the same time.
If you only need to do this for a single entity, consider using WithOneRelated.
let mut world = World::new();
let child2 = world.spawn(Name::new("Child2")).id();
let child3 = world.spawn(Name::new("Child3")).id();
world.spawn((
    Name::new("Root"),
    Children::spawn((
        Spawn(Name::new("Child1")),
        // This adds the already existing entities as children of Root.
        WithRelated::new([child2, child3]),
    )),

fn size_hint(&self) -> usize
Returns a size hint, which is used to reserve space for this list in a 
RelationshipTarget. This should be
less than or equal to the actual size of the list. When in doubt, just use 0.Auto Trait Implementations§
