Constructors

Fields

cpt_arg_tys :: [Type]
The universal arg types 1-1 with the universal tyvars of the constructor/pattern synonym Use (conLikeResTy pat_con cpt_arg_tys) to get the type of the pattern
cpt_tvs :: [TyVar]
Existentially bound type variables in correctly-scoped order e.g. [k:* x:k]
cpt_dicts :: [EvVar]
Ditto *coercion variables* and *dictionaries* One reason for putting coercion variable here I think is to ensure their kinds are zonked
cpt_binds :: TcEvBinds
Bindings involving those dictionaries
cpt_wrap :: HsWrapper

mkCharLitPat :: SourceText -> Char -> LPat GhcTc Source #

mkNilPat :: Type -> LPat GhcTc Source #

isSimplePat :: LPat (GhcPass x) -> Maybe (IdP (GhcPass x)) Source #

Is the pattern any of combination of:

pat :: Type
~pat
!pat
x (variable)

isBangedLPat :: LPat (GhcPass p) -> Bool Source #

patNeedsParens :: forall p. IsPass p => PprPrec -> Pat (GhcPass p) -> Bool Source #

patNeedsParens p pat returns True if the pattern pat needs parentheses under precedence p.

parenthesizePat :: IsPass p => PprPrec -> LPat (GhcPass p) -> LPat (GhcPass p) Source #

parenthesizePat p pat checks if patNeedsParens p pat is true, and if so, surrounds pat with a ParPat. Otherwise, it simply returns pat.
