[−][src]Trait intertrait::CastFrom

pub trait CastFrom: Any + 'static {
    fn ref_any(&self) -> &dyn Any;

    fn mut_any(&mut self) -> &mut dyn Any;

    fn box_any(self: Box<Self>) -> Box<dyn Any>;

    fn rc_any(self: Rc<Self>) -> Rc<dyn Any>;
}

CastFrom must be extended by a trait that wants to allow for casting into another trait.

It is used for obtaining a trait object for Any from a trait object for its sub-trait, and blanket implemented for all Sized + Any + 'static types.

Required methods

fn ref_any(&self) -> &dyn Any

Returns a immutable reference to Any, which is backed by the type implementing this trait.

Returns a mutable reference to Any, which is backed by the type implementing this trait.

fn box_any(self: Box<Self>) -> Box<dyn Any>

Returns a Box of Any, which is backed by the type implementing this trait.

fn rc_any(self: Rc<Self>) -> Rc<dyn Any>

Returns an Rc of Any, which is backed by the type implementing this trait.
