Deriving typeclasses with generics

Plutarch also provides sophisticated generic deriving support for completely custom types. In particular, you can easily derive PlutusType for your own type:

data PMyType (a :: PType) (b :: PType) (s :: S)
  = POne (Term s a)
  | PTwo (Term s b)
  deriving stock Generic
  deriving anyclass PlutusType
instance DerivePlutusType (PMyType a b) where type DPTStrat _ = PlutusTypeScott

Note: This requires the generics-sop package.

This will use a Scott encoding representation for `MyType`, which is typically what you want. If you want to use data encoding representation instead in your PlutusType instance - you should derive it using PlutusTypeData. Check out: implementing PIsDataRepr and friends

Currently, generic deriving supports the following typeclasses:
