class Iso b a => Iso a b where Source #
A class for isomorphic types.
The Iso b a context ensures that transformations in both directions are defined

toBits :: forall a. ArithmeticCircuit a -> [ArithmeticCircuit a] -> Natural -> Natural -> forall i m. MonadBlueprint i a m => m [i] Source #
Convert an ArithmeticCircuit to bits and return their corresponding variables.
fromBits :: forall a. Natural -> Natural -> forall i m. MonadBlueprint i a m => [i] -> m [i] Source #
The inverse of toBits.
getNatural :: forall n. KnownNat n => Natural Source #
maxBitsPerFieldElement :: forall p. Finite p => Natural Source #
The maximum number of bits a Field element can encode.
maxBitsPerRegister :: forall p n. (Finite p, KnownNat n) => Natural Source #
The maximum number of bits it makes sense to encode in a register. That is, if the field elements can encode more bits than required, choose the smaller number.
