Trait SpawnableList

pub trait SpawnableList<R> {
    // Required methods
    fn spawn(self, world: &mut World, entity: Entity);
    fn size_hint(&self) -> usize;
}

A spawn-able list of changes to a given World and relative to a given Entity. This is generally used for spawning “related” entities, such as children.

Required Methods

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.
