pub unsafe trait Capable {
// Required method
fn vtable(capability: TypeId) -> Option<NonNull<()>>;
}Expand description
Used to cast an element to a trait object for a trait it implements.
§Safety
If the vtable function returns Some(p), then p must be a valid pointer
to a vtable of Packed<Self> w.r.t to the trait C where capability is
TypeId::of::<dyn C>().
Required Methods§
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.
