[−][src]Struct user_stable_vtable::refs::StableRef
A type-erased pointer with stable layout to a trait object
This pointer has the same layout as &dyn Trait for #[stable_vtable] traits
as with [RFC 2955].
Note: While &T has special handling when inside Option<T>, no such guarantee is stably made.
There are test suites that check to ensure this is correct.
Also Note: Specifically, this implementation imposes a restriction that the VTable reference be valid for reading for 'a. It is not yet specified the required validity of the vtable
