Implementations§

source§

impl<F: PrimeField> ConstraintSystem<F>

source

pub fn create(gates: Vec<CircuitGate<F>>) -> Builder<F>

Initializes the ConstraintSystem<F> on input gates and fr_sponge_params. Returns a Builder<F> It also defaults to the following values of the builder:

  • public: 0
  • prev_challenges: 0
  • lookup_tables: vec![],
  • runtime_tables: None,
  • precomputations: None,
  • disable_gates_checks: false,

How to use it:

  1. Create your instance of your builder for the constraint system using crate(gates, sponge params)
  2. Iterativelly invoke any desired number of steps: `public(), lookup(), runtime(), precomputations()``
  3. Finally call the build() method and unwrap the Result to obtain your ConstraintSystem
