Synopsis

constructors :: Data ctx a => Proxy ctx -> a -> [Constr]

setFieldFun :: forall m a ctx. (Data ctx m, Typeable a) => Proxy ctx -> Int -> m -> a -> m

constructors :: Data ctx a => Proxy ctx -> a -> [Constr]

Returns a set of constructors. This function is undefined for Int, Float, Double and Char

getFieldFun :: forall a m ctx. (Typeable a, Data ctx m) => Proxy ctx -> Int -> m -> a

A get field fun: parent -> child

setFieldFun :: forall m a ctx. (Data ctx m, Typeable a) => Proxy ctx -> Int -> m -> a -> m

A set field fun: parent -> child -> parent

gToString :: (Show a, Typeable a) => a -> String

Function is similar to show, except that strings are shown without escaped ".
