Struct comfy_wgpu::hecs::With

pub struct With<Q, R>(/* private fields */);

Transforms query Q by skipping entities not satisfying query R

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<&i32, &bool>>()
    .iter()
    .map(|(e, &i)| (e, i))
    .collect::<Vec<_>>();
assert_eq!(entities.len(), 2);
assert!(entities.contains(&(a, 123)));
assert!(entities.contains(&(b, 456)));
