Struct SpawnIter

pub struct SpawnIter<I>(pub I);

A SpawnableList that spawns entities using an iterator of a given Bundle:

let mut world = World::new();
world.spawn((
    Name::new("Root"),
    Children::spawn((
        Spawn(Name::new("Child1")),
        SpawnIter(["Child2", "Child3"].into_iter().map(Name::new)),
    )),
));

Trait Implementations

impl<R: Relationship, I: Iterator<Item = B> + Send + Sync + 'static, B: Bundle> SpawnableList<R> for SpawnIter<I>

fn spawn(self, world: &mut World, entity: Entity)

Spawn this list of changes in a given World and relative to a given Entity. This is generally used for spawning “related” entities, such as children.

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.
