Fields

dcName :: !DcName
Name of the DataCon
dcUniq :: !Unique
Invariant: forall x . dcUniq x ~ nameUniq (dcName x)
dcTag :: !ConTag
Syntactical position in the type definition
dcType :: !Type
Type of the 'DataCon
dcUnivTyVars :: [TyVar]
Universally quantified type-variables, these type variables are also part of the result type of the DataCon
dcExtTyVars :: [TyVar]
Existentially quantified type-variables, these type variables are not part of the result of the DataCon, but only of the arguments.
dcArgTys :: [Type]
Argument types
dcFieldLabels :: [Text]
Names of fields. Used when data constructor is referring to a record type.
