Function bellperson::gadgets::lookup::lookup3_xy_with_conditional_negation [−][src]
pub fn lookup3_xy_with_conditional_negation<E: ScalarEngine, CS>(
cs: CS,
bits: &[Boolean],
coords: &[(E::Fr, E::Fr)]
) -> Result<(Num<E>, Num<E>), SynthesisError> where
CS: ConstraintSystem<E>,
Performs a 3-bit window table lookup, where one of the bits is a sign bit.
