Trait std::ops::DispatchFromDyn

#[lang = "dispatch_from_dyn"]
pub trait DispatchFromDyn<T> { }

🔬 This is a nightly-only experimental API. (dispatch_from_dyn #0)

This is used for object safety, to check that a method's receiver type can be dispatched on.

An example implementation of the trait:

impl<T: ?Sized, U: ?Sized> DispatchFromDyn<Rc<U>> for Rc<T>
where
    T: Unsize<U>,
{}
