Trait Implementations

impl Add for AmountVar

type Output = AmountVar

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self::Output

Performs the + operation.

impl AllocVar<Amount, Fp<MontBackend<FrConfig, 4>, 4>> for AmountVar

fn new_variable<T: Borrow<Amount>>( cs: impl Into<Namespace<Fq>>, f: impl FnOnce() -> Result<T, SynthesisError>, mode: AllocationMode ) -> Result<Self, SynthesisError>

Allocates a new variable of type Self in the ConstraintSystem cs. The mode of allocation is decided by mode.

fn new_constant( cs: impl Into<Namespace<F>>, t: impl Borrow<V> ) -> Result<Self, SynthesisError>

Allocates a new constant of type Self in the ConstraintSystem cs.

fn new_input<T>( cs: impl Into<Namespace<F>>, f: impl FnOnce() -> Result<T, SynthesisError> ) -> Result<Self, SynthesisError>

where T: Borrow<V>,

Allocates a new public input of type Self in the ConstraintSystem cs.

fn new_witness<T>( cs: impl Into<Namespace<F>>, f: impl FnOnce() -> Result<T, SynthesisError> ) -> Result<Self, SynthesisError>

where T: Borrow<V>,

Allocates a new private witness of type Self in the ConstraintSystem cs.

impl AllocVar<Fp<MontBackend<FrConfig, 4>, 4>, Fp<MontBackend<FrConfig, 4>, 4>> for AmountVar

fn new_variable<T: Borrow<Fq>>( cs: impl Into<Namespace<Fq>>, f: impl FnOnce() -> Result<T, SynthesisError>, mode: AllocationMode ) -> Result<Self, SynthesisError>

Allocates a new variable of type Self in the ConstraintSystem cs. The mode of allocation is decided by mode.

fn new_constant( cs: impl Into<Namespace<F>>, t: impl Borrow<V> ) -> Result<Self, SynthesisError>

Allocates a new constant of type Self in the ConstraintSystem cs.

fn new_input<T>( cs: impl Into<Namespace<F>>, f: impl FnOnce() -> Result<T, SynthesisError> ) -> Result<Self, SynthesisError>

where T: Borrow<V>,

Allocates a new public input of type Self in the ConstraintSystem cs.

fn new_witness<T>( cs: impl Into<Namespace<F>>, f: impl FnOnce() -> Result<T, SynthesisError> ) -> Result<Self, SynthesisError>

where T: Borrow<V>,

Allocates a new private witness of type Self in the ConstraintSystem cs.

impl Clone for AmountVar

fn clone(&self) -> AmountVar

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CondSelectGadget<Fp<MontBackend<FrConfig, 4>, 4>> for AmountVar

fn conditionally_select( cond: &Boolean<Fq>, true_value: &Self, false_value: &Self ) -> Result<Self, SynthesisError>

If cond == &Boolean::TRUE, then this returns true_value; else, returns false_value.

fn conditionally_select_power_of_two_vector( position: &[Boolean<ConstraintF>], values: &[Self] ) -> Result<Self, SynthesisError>

Returns an element of values whose index in represented by position. position is an array of boolean that represents an unsigned integer in big endian order.

If should_enforce == true, enforce that self and other are equal; else, enforce a vacuously true statement.

fn enforce_equal(&self, other: &Self) -> Result<(), SynthesisError>

Enforce that self and other are equal.

fn conditional_enforce_not_equal( &self, other: &Self, should_enforce: &Boolean<F> ) -> Result<(), SynthesisError>

If should_enforce == true, enforce that self and other are not equal; else, enforce a vacuously true statement.

fn enforce_not_equal(&self, other: &Self) -> Result<(), SynthesisError>
