    fn get_trait_type_id() -> TraitTypeId;

}

A trait implemented on all values trait object references that can be put into a Value Cell (Vc<Box<dyn Trait>>).

Required Associated Types

type ValueTrait: ?Sized

Required Methods

fn get_trait_type_id() -> TraitTypeId

Returns the type id of the trait object.

fn get_impl_vtables() -> &'static VTableRegistry<Self::ValueTrait>

Returns the vtable for an implementation of this trait. Panics if ValueTypeId does not implement the trait.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
