[−][src]Struct hecs::Without

pub struct Without<T, Q>(_);

Query transformer skipping entities that have a T component

See also QueryBorrow::without.

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::<Without<bool, &i32>>()
    .iter()
    .map(|(e, &i)| (e, i))
    .collect::<Vec<_>>();
assert_eq!(entities, &[(c, 42)]);
