Expand description

Helper for ty_or_const_infer_var_changed (see comment on that), currently used only for traits::fulfill’s list of stalled_on inference variables.

Variants

`Ty(TyVid)`

Equivalent to ty::Infer(ty::TyVar(_)).

`TyInt(IntVid)`

Equivalent to ty::Infer(ty::IntVar(_)).

`TyFloat(FloatVid)`

Equivalent to ty::Infer(ty::FloatVar(_)).

`Const(ConstVid<'tcx>)`

Equivalent to ty::ConstKind::Infer(ty::InferConst::Var(_)).
