newtype Override a (xs :: [*])

The feature of this library. For use with DerivingVia. Apply it to a type a and supply a type-level list of instance overrides xs.

type Rep (Override a xs)

Defined in Data.Override.Internal

type Rep (Override a xs) = OverrideRep xs (Rep a)

data As (o :: k) n

Used to construct a type-level override. Usually used infix. The o should be either a type (kind *) or a type-level string (kind Symbol).

data With (o :: k) (w :: * -> *)

Used to wrap a field into a something of kind * -> *, for example another newtype.
