data RootResolver (m :: Type -> Type) event (query :: (Type -> Type) -> Type) (mutation :: (Type -> Type) -> Type) (subscription :: (Type -> Type) -> Type)

GraphQL Root resolver, also the interpreter generates a GQL schema from it. queryResolver is required, mutationResolver and subscriptionResolver are optional, if your schema does not supports mutation or subscription , you can use () for it.

Constructors
