Struct snarkvm_wasm::fields::AllocatedFp[−][src]

pub struct AllocatedFp<F> where
    F: PrimeField,  {
    pub value: Option<F>,

}
Expand description

Represents a variable in the constraint system whose value can be an arbitrary field element.

Fields

value: Option<F>variable: ConstraintVariable<F>

Implementations

impl<F> AllocatedFp<F> where
    F: PrimeField, [src]

pub fn from<CS>(cs: CS, value: &F) -> AllocatedFp<F> where
    CS: ConstraintSystem<F>, [src]

impl<F> AllocatedFp<F> where
    F: PrimeField, [src]

pub fn from_boolean<CS>(
    cs: CS,
    other: Boolean
) -> Result<AllocatedFp<F>, SynthesisError> where
    CS: ConstraintSystem<F>, [src]

Constructs Self from a Boolean: if other is false, this outputs zero, else it outputs one.

pub fn is_neq<CS>(
    &self,
    cs: CS,
    other: &AllocatedFp<F>
) -> Result<Boolean, SynthesisError> where
    CS: ConstraintSystem<F>, [src]

Outputs the bit self != other.

This requires three constraints.
