Description

Derive constructor-field-type-based prisms generically.

Synopsis

type Context a s = (Generic s, ErrorUnlessOne a s (CollectPartialType (TupleToList a) (Rep s)), GAsType (Rep s) a, Defined (Rep s) (NoGeneric s '['Text "arising from a generic prism focusing on a constructor of type " :<>: QuoteType a]) (() :: Constraint)) Source #

derived :: Context a s => Prism' s a Source #

class GAsType (f :: Type -> Type) (as :: Type) where Source #

As AsType but over generic representations as defined by GHC.Generics.
