Struct snarkvm_wasm::gm17::KeypairAssembly

pub struct KeypairAssembly<E> where
    E: PairingEngine,  {
    pub num_public_variables: usize,
    pub num_private_variables: usize,
    pub num_constraints: usize,
    pub at: Vec<Vec<(<E as PairingEngine>::Fr, Index), Global>, Global>,
    pub bt: Vec<Vec<(<E as PairingEngine>::Fr, Index), Global>, Global>,
    pub ct: Vec<Vec<(<E as PairingEngine>::Fr, Index), Global>, Global>,
}

This is our assembly structure that we’ll use to synthesize the circuit into a SAP.

Trait Implementations

impl<E> ConstraintSystem<<E as PairingEngine>::Fr> for KeypairAssembly<E> where
    E: PairingEngine, 

type Root = KeypairAssembly<E>

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

pub fn alloc<F, A, AR>(&mut self, A, F) -> Result<Variable, SynthesisError> where
    A: FnOnce() -> AR,
    F: FnOnce() -> Result<<E as PairingEngine>::Fr, SynthesisError>,
    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.

pub fn alloc_input<F, A, AR>(
    &mut self,
    A,
    F
) -> Result<Variable, SynthesisError> where
    A: FnOnce() -> AR,
    F: FnOnce() -> Result<<E as PairingEngine>::Fr, SynthesisError>,
    AR: AsRef<str>, 

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

pub fn enforce<A, AR, LA, LB, LC>(&mut self, A, a: LA, b: LB, c: LC) where
    LC: FnOnce(LinearCombination<<E as PairingEngine>::Fr>) -> LinearCombination<<E as PairingEngine>::Fr>,
    A: FnOnce() -> AR,
    AR: AsRef<str>,
    LA: FnOnce(LinearCombination<<E as PairingEngine>::Fr>) -> LinearCombination<<E as PairingEngine>::Fr>,
    LB: FnOnce(LinearCombination<<E as PairingEngine>::Fr>) -> LinearCombination<<E as PairingEngine>::Fr>, 

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.

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

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

pub fn pop_namespace(&mut self)

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

pub fn get_root(
    &mut self
) -> &mut <KeypairAssembly<E> as ConstraintSystem<<E as PairingEngine>::Fr>>::Root

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

pub fn num_constraints(&self) -> usize

Output the number of constraints in the system.

pub fn num_public_variables(&self) -> usize

Output the number of public input variables to the system.

pub fn num_private_variables(&self) -> usize

Output the number of private input variables to the system.

fn one() -> Variable

Return the “one” input variable

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

Begin a namespace for this constraint system.
