impl<T> Downcast for Twhere T: Any,

source§

fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>

Convert Box<Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
source§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>

Convert Rc<Trait> (where Trait: Downcast) to Rc<dyn Any>. Rc<dyn Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.
source§

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

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

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

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

impl<T> DowncastSync for Twhere T: Any + Send + Sync,

source§

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Send + Sync + 'static>

Convert Arc<Trait> (where Trait: Downcast) to Arc<dyn Any>. Arc<dyn Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
