ForAllTyFlags

data ForAllTyFlag Source #

ForAllTyFlag

Is something required to appear in source Haskell (Required), permitted by request (Specified) (visible type application), or prohibited entirely from appearing in source Haskell (Inferred)? See Note [VarBndrs, ForAllTyBinders, TyConBinders, and visibility] in GHC.Core.TyCo.Rep

Constructors

Invisible !Specificity
Required

data Specificity Source #

Whether an Invisible argument may appear in source Haskell.

Constructors

InferredSpec	the argument may not appear in source Haskell, it is only inferred.
SpecifiedSpec	the argument may appear in source Haskell, but isn't required.
