Bind a HRec of named fields containing all the specified fields.

pfield :: forall name b p s a as n. (PDataFields p, as ~ PFields p, n ~ PLabelIndex name as, KnownNat n, a ~ PUnLabel (IndexList n as), PFromDataable a b) => Term s (p :--> b) Source #

Get a single field from a Term.

NB*: If you access more than one field from the same value you should use pletFields instead, which will generate the bindings more efficiently.

type HRecOf t fs s = HRec (BoundTerms (PFields t) (Bindings (PFields t) fs) s) Source #

The HRec yielded by 'pletFields @fs t'.

type family PMemberFields t fs s as where ... Source #

Constrain an HRec to contain the specified fields from the given Plutarch type.

Example ===

import qualified GHC.Generics as GHC
import Generics.SOP

import Plutarch.Prelude
import Plutarch.DataRepr

newtype PFooType s = PFooType (Term s (PDataRecord '["frst" ':= PInteger, "scnd" ':= PBool, "thrd" ':= PString]))
  deriving stock (GHC.Generic)
  deriving anyclass (Generic)
  deriving anyclass (PIsDataRepr)
  deriving
    (PlutusType, PIsData, PDataFields, PEq)
    via PIsDataReprInstances PFooType

foo :: PMemberFields PFooType '["scnd", "frst"] s as => HRec as -> Term s PInteger
foo h = pif (getField "scnd" h) (getField "frst" h) 0

type family PMemberField t name s as where ... Source #

Single field version of PMemberFields.
