std::ops::DispatchFromDyn - Rust
Description: API documentation for the Rust `DispatchFromDyn` trait in crate `std`.
Keywords: rust, rustlang, rust-lang, DispatchFromDyn

# [−][src]Trait std::ops::DispatchFromDyn

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

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

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>,
    {}

Run
