[−][src]Enum rustc_trait_selection::infer::TyOrConstInferVar

pub enum TyOrConstInferVar<'tcx> {
    Ty(TyVid),
    TyInt(IntVid),
    TyFloat(FloatVid),
    Const(ConstVid<'tcx>),
}

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(_)).
