Trait Implementations

impl<F: Field> ConstraintSystem<F> for TestConstraintChecker<F>

type Root = TestConstraintChecker<F>

Represents the type of the “root” of this constraint system so that nested namespaces can minimize indirection.

fn alloc<Fn, A, AR>( &mut self, _annotation: A, f: Fn ) -> Result<Variable, SynthesisError>where Fn: FnOnce() -> Result<F, SynthesisError>, A: FnOnce() -> AR, AR: AsRef<str>,

Allocate a private variable in the constraint system. The provided function is used to determine the assignment of the variable. The given annotation function is invoked in testing contexts in order to derive a unique name for this variable in the current namespace.

fn alloc_input<Fn, A, AR>( &mut self, _annotation: A, f: Fn ) -> Result<Variable, SynthesisError>where Fn: FnOnce() -> Result<F, SynthesisError>, A: FnOnce() -> AR, AR: AsRef<str>,

Allocate a public variable in the constraint system. The provided function is used to determine the assignment of the variable.

fn enforce<A, AR, LA, LB, LC>(&mut self, annotation: A, a: LA, b: LB, c: LC)where A: FnOnce() -> AR, AR: AsRef<str>, LA: FnOnce(LinearCombination<F>) -> LinearCombination<F>, LB: FnOnce(LinearCombination<F>) -> LinearCombination<F>, LC: FnOnce(LinearCombination<F>) -> LinearCombination<F>,

Enforce that A * B = C. The annotation function is invoked in testing contexts in order to derive a unique name for the constraint in the current namespace.

fn push_namespace<NR: AsRef<str>, N: FnOnce() -> NR>(&mut self, name_fn: N)

Create a new (sub)namespace and enter into it. Not intended for downstream use; use namespace instead.

fn pop_namespace(&mut self)

Exit out of the existing namespace. Not intended for downstream use; use namespace instead.

fn get_root(&mut self) -> &mut Self::Root

Gets the “root” constraint system, bypassing the namespacing. Not intended for downstream use; use namespace instead.

fn num_constraints(&self) -> usize

Output the number of constraints in the system.

fn num_public_variables(&self) -> usize

Output the number of public input variables to the system.

fn num_private_variables(&self) -> usize

Output the number of private input variables to the system.

fn is_in_setup_mode(&self) -> bool

Output whether the constraint system is in the setup mode.

fn one() -> Variable

Return the “one” input variable

fn ns<NR, N>(&mut self, name_fn: N) -> Namespace<'_, F, Self::Root>where NR: AsRef<str>, N: FnOnce() -> NR,

Begin a namespace for this constraint system.

impl<F: Field> Default for TestConstraintChecker<F>

fn default() -> Self

Returns the “default value” for a type.
