Implementations§

impl ComponentSparseSet

Returns a reference to the entity’s component value.

Returns None if entity does not have a component in the sparse set.

Returns None if entity does not have a component in the sparse set.

pub fn get_added_tick(&self, entity: Entity) -> Option<&UnsafeCell<Tick>>

impl<T> Downcast for T
where T: Any,

fn into_any(self: Box<T>) -> Box<dyn Any>

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
