gmappend :: (Generic a, GSemigroup (Rep a)) => a -> a -> a Source #

Generically generate a `Semigroup` (`<>`) operation for any type implementing `Generic`. This operation will append two values by point-wise appending their component fields. It is only defined for product types.

    gmappend a (gmappend b c) = gmappend (gmappend a b) c

gmempty :: (Generic a, GMonoid (Rep a)) => a Source #

Generically generate a `Monoid` `mempty` for any product-like type implementing `Generic`.

It is only defined for product types.

    gmappend gmempty a = a = gmappend a gmempty
