[−]Trait tract_hir::internal::tract_downcast_rs::Downcast

pub trait Downcast: Any {
    fn into_any(self: Box<Self>) -> Box<dyn Any + 'static>;

    fn into_any_rc(self: Rc<Self>) -> Rc<dyn Any + 'static>;

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

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

Supports conversion to Any. Traits to be extended by impl_downcast! must extend Downcast.

Required methods

fn into_any(self: Box<Self>) -> Box<dyn Any + 'static>

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

fn into_any_rc(self: Rc<Self>) -> Rc<dyn Any + 'static>

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

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.
