- data Rec where

A record is parameterized by a list of fields and a functor to be applied to each of those fields.
|(Storable t, Storable (PlainRec rs)) => Storable (PlainRec (: * (::: sy t) rs))|
|Storable (PlainRec ( *))|
|Dist (Rec rs)|
Records may be distributed to accumulate the effects of their fields.
|(Eq (g t), Eq (Rec fs g)) => Eq (Rec (: * (::: s t) fs) g)|
|Eq (Rec ( *) f)|
|(SingI Symbol sy, Show (g t), Show (Rec fs g)) => Show (Rec (: * (::: sy t) fs) g)|
|Show (Rec ( *) f)|
|(Monoid t, Monoid (Rec fs g), Applicative g) => Monoid (Rec (: * (::: s t) fs) g)|
|Monoid (Rec ( *) f)|
|FoldRec (Rec ( *) f) a|
|FoldRec (Rec fs g) (g t) => FoldRec (Rec (: * (::: s t) fs) g) (g t)|
|Apply (* -> *) (~> *) (Rec rs)|
Records can be applied to each other.
|(~ * y (::: sy t), IElem * y xs, <: (Rec xs f) (Rec ys f)) => (Rec xs f) <: (Rec (: * y ys) f)|
|(Rec xs f) <: (Rec ( *) f)|
Shorthand for a record with a single field. Lifts the field's value into the chosen functor automatically.
