}Fields
upcast_trait_ref: Binder<'tcx, TraitRef<'tcx>>Foo upcast to the obligation trait. This will be some supertrait of Foo.
vtable_vptr_slot: Option<usize>The vtable is formed by concatenating together the method lists of
the base object trait and all supertraits, pointers to supertrait vtable will
be provided when necessary; this is the position of upcast_trait_ref’s vtable
within that vtable.

Layout
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
