Struct G1PreparedVar

pub struct G1PreparedVar<P: Bls12Config>(pub AffineVar<P::G1Config, FpVar<P::Fp>>);

Represents the cached precomputation that can be performed on a G1 element which enables speeding up pairing computation.

Tuple Fields

0: AffineVar<P::G1Config, FpVar<P::Fp>>

Implementations

impl<P: Bls12Config> G1PreparedVar<P>

pub fn value(&self) -> Result<G1Prepared<P>, SynthesisError>

Returns the value assigned to self in the underlying constraint system.

pub fn from_group_var(q: &G1Var<P>) -> Result<Self, SynthesisError>

Constructs Self from a G1Var.

Trait Implementations

impl<P: Bls12Config> AllocVar<G1Prepared<P>, <P as Bls12Config>::Fp> for G1PreparedVar<P>

fn new_variable<T: Borrow<G1Prepared<P>>>( cs: impl Into<Namespace<P::Fp>>, 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: Borrow<V>>( cs: impl Into<Namespace<F>>, f: impl FnOnce() -> Result<T, SynthesisError>, ) -> Result<Self, SynthesisError>

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

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

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

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

Allocates a new constant or private witness of type Self in the ConstraintSystem cs with the allocation mode inferred from cs. A constant is allocated if cs is None, and a private witness is allocated otherwise.

impl<P: Bls12Config> Clone for G1PreparedVar<P>

where AffineVar<P::G1Config, FpVar<P::Fp>>: Clone,

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<P: Bls12Config> Debug for G1PreparedVar<P>

where AffineVar<P::G1Config, FpVar<P::Fp>>: Debug,

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

Formats the value using the given formatter.

impl<P: Bls12Config> ToBytesGadget<<P as Bls12Config>::Fp> for G1PreparedVar<P>

fn to_bytes_le(&self) -> Result<Vec<UInt8<P::Fp>>, SynthesisError>

Outputs a canonical, little-endian, byte decomposition of self.

fn to_non_unique_bytes_le(&self) -> Result<Vec<UInt8<P::Fp>>, SynthesisError>

Outputs a possibly non-unique byte decomposition of self.
