pub fn def_id(&self) -> DefId
sourcepub fn with_self_ty(
&self,

pub fn with_self_ty(

) -> PolyTraitRef<'tcx>
Object types don’t have a self type specified. Therefore, when
we convert the principal trait-ref into a normal trait-ref,
you must give some self type. A common choice is mk_err()
or some placeholder type.
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.
