Type Alias bones_ecs::system::CompMut

pub type CompMut<'a, T> = RefMut<'a, ComponentStore<T>>;

SystemParam for getting mutable access to a ComponentStore.

Aliased Type

struct CompMut<'a, T> { /* private fields */ }

Trait Implementations

impl<'a, 'q, T: HasSchema> QueryItem for &'a CompMut<'q, T>

type Iter = Map<UntypedComponentBitsetIterator<'a>, for<'b> fn(_: SchemaRef<'b>) -> &'b 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<<Self::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>) -> Self::Iter

Return an iterator over the provided bitset.

impl<'a, 'q, T: HasSchema> QueryItem for &'a mut CompMut<'q, T>

type Iter = Map<UntypedComponentBitsetIteratorMut<'a>, for<'b> fn(_: SchemaRefMut<'b>) -> &'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<<Self::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>) -> Self::Iter

Return an iterator over the provided bitset.

impl<'a, T: HasSchema> SystemParam for CompMut<'a, T>

type State = Arc<AtomicCell<ComponentStore<T>>>

The intermediate state for the parameter, that may be extracted from the world.

type Param<'p> = RefMut<'p, ComponentStore<T>>

The type of the parameter, ranging over the lifetime of the intermediate state.

fn get_state(world: &World) -> Self::State

This is called to produce the intermediate state of the system parameter.

fn borrow<'s>(_world: &'s World, state: &'s mut Self::State) -> Self::Param<'s>

This is used create an instance of the system parame, possibly borrowed from the intermediate parameter state.
