Struct oxygengine_core::ecs::With
source · [−]pub struct With<T, Q>(_);Expand description
Query transformer skipping entities that do not have a T component
See also QueryBorrow::with.
Example
let mut world = World::new();
let a = world.spawn((123, true, "abc"));
let b = world.spawn((456, false));
let c = world.spawn((42, "def"));
let entities = world.query::<With<bool, &i32>>()
.iter()
.map(|(e, &i)| (e, i))
.collect::<Vec<_>>();
assert_eq!(entities.len(), 2);
assert!(entities.contains(&(a, 123)));
assert!(entities.contains(&(b, 456)));Trait Implementations
