wantedEvId_maybe :: Ct -> Maybe EvVarghc-lib-parser GHC.Tc.Types.Constraint Returns the evidence Id for the argument Ct when this Ct is a Wanted. Returns Nothing otherwise.

isSigMaybe :: UserTypeCtxt -> Maybe Nameghc-lib-parser GHC.Tc.Types.Origin No documentation available.
anyTy_maybe :: Type -> Maybe Kindghc-lib-parser GHC.Tc.Utils.TcType Check whether the type is of the form Any :: k, returning the kind k.
checkingExpType_maybe :: ExpType -> Maybe TcTypeghc-lib-parser GHC.Tc.Utils.TcType Returns the expected type when in checking mode.
getCastedTyVar_maybe :: Type -> Maybe (TyVar, CoercionN)ghc-lib-parser GHC.Tc.Utils.TcType If the type is a tyvar, possibly under a cast, returns it, along with the coercion. Thus, the co is :: kind tv ~N kind ty
getTyVar_maybe :: Type -> Maybe TyVarghc-lib-parser GHC.Tc.Utils.TcType Attempts to obtain the type variable underlying a Type
isConcreteTyVarTy_maybe :: TcType -> Maybe (TcTyVar, ConcreteTvOrigin)ghc-lib-parser GHC.Tc.Utils.TcType Is this type a concrete type variable? If so, return the associated TcTyVar and ConcreteTvOrigin.
