Constructors

ConPatTc

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
Extra wrapper to pass to the matcher Only relevant for pattern-synonyms; ignored for data cons

data XXPatGhcTc Source #

Extension constructor for Pat, added after typechecking.

Constructors

CoPat

Coercion Pattern (translation only)

During desugaring a (CoPat co pat) turns into a cast with co on the scrutinee, followed by a match on pat.

Fields

co_cpt_wrap :: HsWrapper
Coercion Pattern If co :: t1 ~ t2, p :: t2, then (CoPat co p) :: t1
co_pat_inner :: Pat GhcTc
Why not LPat? Ans: existing locn will do
co_pat_ty :: Type
Type of whole pattern, t1

ExpansionPat (Pat GhcRn) (Pat GhcTc)

Pattern expansion: original pattern, and desugared pattern, for RebindableSyntax and other overloaded syntax such as OverloadedLists. See Note [Rebindable syntax and HsExpansion].
