fn deserialize_uncompressed<R: Read>(
    reader: &mut R
) -> Result<Self, SerializationError>

Reads Self from reader without compression.

impl<E: PairingEngine> CanonicalSerialize for KeypairAssembly<E>

fn serialize<W: Write>(&self, writer: &mut W) -> Result<(), SerializationError>

Serializes self into writer.

fn serialized_size(&self) -> usize

fn serialize_uncompressed<W: Write>(
    &self,
    writer: &mut W
) -> Result<(), SerializationError>

Serializes self into writer without compression.

fn uncompressed_size(&self) -> usize

impl<E: Clone + PairingEngine> Clone for KeypairAssembly<E> where
    E::Fr: Clone,
    E::Fr: Clone,
    E::Fr: Clone, 

fn clone(&self) -> KeypairAssembly<E>

Returns a copy of the value.

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

Performs copy-assignment from source.

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

type Root = Self

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

fn alloc<F, A, AR>(&mut self, _: A, _: F) -> Result<Variable, SynthesisError> where
    F: FnOnce() -> Result<E::Fr, 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<F, A, AR>(
    &mut self,
    _: A,
    _: F
) -> Result<Variable, SynthesisError> where
    F: FnOnce() -> Result<E::Fr, 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, _: A, a: LA, b: LB, c: LC) where
    A: FnOnce() -> AR,
    AR: AsRef<str>,
    LA: FnOnce(LinearCombination<E::Fr>) -> LinearCombination<E::Fr>,
    LB: FnOnce(LinearCombination<E::Fr>) -> LinearCombination<E::Fr>,
    LC: FnOnce(LinearCombination<E::Fr>) -> LinearCombination<E::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.

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

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<E: Debug + PairingEngine> Debug for KeypairAssembly<E> where
    E::Fr: Debug,
    E::Fr: Debug,
    E::Fr: Debug, 

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

Formats the value using the given formatter.
