pub struct SourceComponent<'a> { /* private fields */ }Expand description
Provides read access to the source component (the component being cloned) in a ComponentCloneFn.
Implementations§
Source§impl<'a> SourceComponent<'a>
impl<'a> SourceComponent<'a>
Sourcepub fn read<C: Component>(&self) -> Option<&C>
pub fn read<C: Component>(&self) -> Option<&C>
Returns a reference to the component on the source entity.
Will return None if ComponentId of requested component does not match ComponentId of source component
Sourcepub fn read_reflect(&self, registry: &TypeRegistry) -> Option<&dyn Reflect>
Available on crate feature bevy_reflect only.
pub fn read_reflect(&self, registry: &TypeRegistry) -> Option<&dyn Reflect>
bevy_reflect only.Returns a reference to the component on the source entity as &dyn Reflect.
Will return None if:
- World does not have
AppTypeRegistry. - Component does not implement
ReflectFromPtr. - Component is not registered.
- Component does not have
TypeId - Registered
ReflectFromPtr’sTypeIddoes not match component’sTypeId

fn into_any(self: Box<T>) -> Box<dyn Any>
Converts
Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>, which can then be
downcast into Box<dyn ConcreteType> where ConcreteType implements Trait.Source§fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Converts
Rc<Trait> (where Trait: Downcast) to Rc<Any>, which can then be further
downcast into Rc<ConcreteType> where ConcreteType implements Trait.Source§fn as_any(&self) -> &(dyn Any + 'static)
fn as_any(&self) -> &(dyn Any + 'static)
Converts
&Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &Any’s vtable from &Trait’s.Source§fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
Converts
&mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &mut Any’s vtable from &mut Trait’s.
