Expand description

The A, B and C matrices of a Rank-One ConstraintSystem. Also contains metadata on the structure of the constraint system and the matrices.

Fields

num_instance_variables: usize

The number of variables that are “public instances” to the constraint system.

num_witness_variables: usize

The number of variables that are “private witnesses” to the constraint system.

num_constraints: usize

The number of constraints in the constraint system.

a_num_non_zero: usize

The number of non_zero entries in the A matrix.

b_num_non_zero: usize

The number of non_zero entries in the B matrix.

c_num_non_zero: usize

The number of non_zero entries in the C matrix.

a: Matrix<F>

The A constraint matrix. This is empty when self.mode == SynthesisMode::Prove { construct_matrices = false }.

b: Matrix<F>

The B constraint matrix. This is empty when self.mode == SynthesisMode::Prove { construct_matrices = false }.

c: Matrix<F>

The C constraint matrix. This is empty when self.mode == SynthesisMode::Prove { construct_matrices = false }.
