Enum rustc_middle::ty::context::UserType [−][src]
pub enum UserType<'tcx> { Ty(Ty<'tcx>), TypeOf(DefId, UserSubsts<'tcx>), }
A user-given type annotation attached to a constant. These arise
from constants that are named via paths, like Foo::<A>::new
and
so forth.
Variants
Ty(Ty<'tcx>)
TypeOf(DefId, UserSubsts<'tcx>)
The canonical type is the result of type_of(def_id)
with the
given substitutions applied.
