Struct ConstraintSystem 

pub struct ConstraintSystem {
    pub variables: Vec<Variable>,
    pub constraints: Vec<Constraint>,
    pub num_public_inputs: usize,
    pub public_input_indices: Vec<usize>,
}

A constraint system accumulating R1CS constraints.

Fields

variables: Vec<Variable>

All allocated variables.

constraints: Vec<Constraint>

All constraints.

num_public_inputs: usize

Number of public input variables.

public_input_indices: Vec<usize>

Indices of public input variables.

Implementations

impl ConstraintSystem

pub fn new() -> Self

Create a new empty constraint system.

pub fn num_variables(&self) -> usize

Number of variables.

pub fn num_constraints(&self) -> usize

Number of constraints.

pub fn is_satisfied(&self) -> bool

Check if all constraints are satisfied by the current variable assignments.

Trait Implementations

impl Clone for ConstraintSystem

fn clone(&self) -> ConstraintSystem

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ConstraintSystem

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ConstraintSystem

fn default() -> Self

Returns the “default value” for a type.
