Struct rustc::traits::VtableObjectData [−] [src]

pub struct VtableObjectData<'tcx, N> {
    pub upcast_trait_ref: PolyTraitRef<'tcx>,
    pub vtable_base: usize,
    pub nested: Vec<N>,
}
Unstable (rustc_private)

A vtable for some object-safe trait Foo automatically derived for the object type Foo.

Fields

upcast_trait_ref: PolyTraitRef<'tcx>
Unstable (rustc_private)

Foo upcast to the obligation trait. This will be some supertrait of Foo.

vtable_base: usize
Unstable (rustc_private)

The vtable is formed by concatenating together the method lists of the base object trait and all supertraits; this is the start of upcast_trait_ref's methods in that vtable.

nested: Vec<N>
Unstable (rustc_private)
