pub struct CheckStorage<'a, T, D> { /* fields omitted */ }

A storage type that iterates entities that have a particular component type, but does not return the component.

Trait Implementations

impl<'a, 'e, T, D> Join for &'a CheckStorage<'e, T, D>

type Type = Entry<'a, 'e, T, D>

Type of joined components.

type Value = *const Storage<'e, T, D>

Type of joined storages.

type Mask = &'a BitSet

Type of joined bit mask.

fn open(self) -> (Self::Mask, Self::Value)

Open this join by returning the mask and the storages.

unsafe fn get(
    storage: &mut *const Storage<'e, T, D>,
    id: Index
) -> Entry<'a, 'e, T, D>

Get a joined component value by a given index.

fn join(self) -> JoinIter<Self> where
    Self: Sized, 

Create a joined iterator over the contents.

impl<'a, 'e, T, D> Not for &'a CheckStorage<'e, T, D>

type Output = AntiStorage<'a>

The resulting type after applying the ! operator.

fn not(self) -> Self::Output

Performs the unary ! operation.
