Struct rustc_trait_selection::traits::ImplSourceObjectData

source · 
pub struct ImplSourceObjectData<'tcx, N> {
    pub upcast_trait_ref: Binder<'tcx, TraitRef<'tcx>>,
    pub vtable_base: usize,
    pub nested: Vec<N, Global>,
}

Fields§

§upcast_trait_ref: Binder<'tcx, TraitRef<'tcx>>

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

§vtable_base: 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 start of upcast_trait_ref’s methods in that vtable.

§nested: Vec<N, Global>

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.
