conLikeArity :: ConLike -> Arity Source #

Number of arguments

conLikeFieldLabels :: ConLike -> [FieldLabel] Source #

Names of fields used for selectors

conLikeInstOrigArgTys :: ConLike -> [Type] -> [Type] Source #

Returns just the instantiated *value* argument types of a `ConLike`

,
(excluding dictionary args)

conLikeExTyCoVars :: ConLike -> [TyCoVar] Source #

Existentially quantified type/coercion variables

conLikeName :: ConLike -> Name Source #

conLikeWrapId_maybe :: ConLike -> Maybe Id Source #

Returns the `Id`

of the wrapper. This is also known as the builder in
some contexts. The value is Nothing only in the case of unidirectional
pattern synonyms.

conLikeImplBangs :: ConLike -> [HsImplBang] Source #

Returns the strictness information for each constructor

conLikeFullSig :: ConLike -> ([TyVar], [TyCoVar], [EqSpec], ThetaType, ThetaType, [Type], Type) Source #

The "full signature" of the `ConLike`

returns, in order:

1) The universally quantified type variables

2) The existentially quantified type/coercion variables

3) The equality specification

4) The provided theta (the constraints provided by a match)

5) The required theta (the constraints required for a match)

6) The original argument types (i.e. before any change of the representation of the type)

7) The original result type

conLikeFieldType :: ConLike -> FieldLabelString -> Type Source #

Extract the type for any given labelled field of the `ConLike`

conLikesWithFields :: [ConLike] -> [FieldLabelString] -> [ConLike] Source #

The ConLikes that have *all* the given fields

conLikeIsInfix :: ConLike -> Bool Source #
