data ConPatTc Source #

This is the extension field for ConPat, added after typechecking It adds quite a few extra fields, to support elaboration of pattern matching.

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

hsRecFieldsArgs :: UnXRec p => HsRecFields p arg -> [arg] Source #

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

Is the pattern any of combination of:

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

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

gParPat :: forall (pass :: Pass). LPat (GhcPass pass) -> Pat (GhcPass pass) Source #

Parenthesize a pattern without token information

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

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

parenthesizePat :: forall (p :: Pass). 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.

isIrrefutableHsPat Source #

Arguments

:: forall (p :: Pass). OutputableBndrId p 
=> Bool

Are we in a -XStrict context? See Note [-XStrict and irrefutability]

-> LPat (GhcPass p) 
-> Bool 

(isIrrefutableHsPat p) is true if matching against p cannot fail in the sense of falling through to the next pattern. (NB: this is not quite the same as the (silly) defn in 3.17.2 of the Haskell 98 report.)

WARNING: isIrrefutableHsPat returns False if it's in doubt. Specifically on a ConPatIn, which is what it sees for a (LPat Name) in the renamer, it doesn't know the size of the constructor family, so it returns False. Result: only tuple patterns are considered irrefutable at the renamer stage.

But if it returns True, the pattern is definitely irrefutable

isBoringHsPat :: forall (p :: Pass). OutputableBndrId p => LPat (GhcPass p) -> Bool Source #

Is this pattern boring from the perspective of pattern-match checking, i.e. introduces no new pieces of long-dinstance information which could influence pattern-match checking?

See Note [Boring patterns].
