Struct shipyard::Not[−][src]

pub struct Not<T>(_);

Used to filter out components.

Get and iterators will skip entities that have this component.
Simply add ! in front of the view reference at iterator creation.

Example

use shipyard::{IntoIter, View, World};

let mut world = World::new();

world.add_entity((0usize, 1u32));
world.add_entity((2usize,));

let (usizes, u32s) = world.borrow::<(View<usize>, View<u32>)>().unwrap();

let mut iter = (&usizes, !&u32s).iter();
assert_eq!(iter.next(), Some((&2, ())));
assert_eq!(iter.next(), None);
let mut iter = (&usizes, &u32s).iter();
assert_eq!(iter.next(), Some((&0, &1)));
assert_eq!(iter.next(), None);
