impl<T> Clone for ComponentChangedFilter<T> where
    T: Component, 

fn clone(&self) -> ComponentChangedFilter<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T> Debug for ComponentChangedFilter<T> where
    T: Component + Debug, 

fn fmt(&self, f: &mut Formatter) -> Result<(), Error>

Formats the value using the given formatter.

impl<'a, T> Filter<ChunkFilterData<'a>> for ComponentChangedFilter<T> where
    T: Component, 

type Iter = ComponentChangedState<'a, ComponentStorage>

fn init(&self)

fn collect(
    &self,
    source: ChunkFilterData<'a>
) -> <ComponentChangedFilter<T> as Filter<ChunkFilterData<'a>>>::Iter

Pulls iterator data out of the source.

fn is_match(
    &self,
    item: &<<ComponentChangedFilter<T> as Filter<ChunkFilterData<'a>>>::Iter as Iterator>::Item
) -> Option<bool>

Determines if an element of Self::Iter matches the filter conditions.

fn matches(&mut self, source: T) -> FilterIter<Self, T>

Creates an iterator which yields bools for each element in the source which indicate if the element matches the filter.
