Struct bones_lib::ecs::entities::OptionalQueryItemMut

pub struct OptionalQueryItemMut<'a, T, S>(pub &'a mut S, pub PhantomData<&'a T>)
where
    T: HasSchema;
Expand description

Wrapper for the CompMut SystemParam used as QueryItem to iterate over entities optionally and mutably retrieving components from ComponentStore. Entities iterated over will not be filtered by OptionalQueryItemMut.

See OptionalMut helper func for constructing OptionalQueryItemMut and usage

Trait Implementations§

§

impl<'a, T, S, C> QueryItem for &'a mut OptionalQueryItemMut<'a, T, S>
where T: HasSchema, C: ComponentIterBitset<'a, T> + 'a, S: DerefMut<Target = C> + 'a,

Mutably iterate over optional component with syntax: &mut OptionalMut(&mut RefMut<ComponentStore<T>>)

§

type Iter = Map<UntypedComponentOptionalBitsetIteratorMut<'a>, for<'b> fn(_: Option<SchemaRefMut<'b>>) -> Option<&'b mut T>>

The type of iterator this query item creates
§

fn apply_bitset(&self, _bitset: &mut BitSetVec)

Modify the iteration bitset
§

fn get_single_with_bitset( self, bitset: Rc<BitSetVec>, ) -> Result<<<&'a mut OptionalQueryItemMut<'a, T, S> as QueryItem>::Iter as Iterator>::Item, QuerySingleError>

Return the item that matches the query within the given bitset if there is exactly one entity that matches this query item.
§

fn iter_with_bitset( self, bitset: Rc<BitSetVec>, ) -> <&'a mut OptionalQueryItemMut<'a, T, S> as QueryItem>::Iter

Return an iterator over the provided bitset.
