pub enum Assigned<F> {
Zero,
Trivial(F),
Rational(F, F),
}Expand description
A value assigned to a cell within a circuit.
Stored as a fraction, so the backend can use batch inversion.
A denominator of zero maps to an assigned value of zero.
Variants§
Zero
The field element zero.
Trivial(F)
A value that does not require inversion to evaluate.
Rational(F, F)
A value stored as a fraction to enable batch inversion.
