Struct snarkvm_r1cs::Namespace

source ·
pub struct Namespace<'a, F: Field, CS: ConstraintSystem<F>>(_, _);
Expand description

This is a “namespaced” constraint system which borrows a constraint system (pushing a namespace context) and, when dropped, pops out of the namespace context.

Trait Implementations§

source§

impl<F: Field, CS: ConstraintSystem<F>> ConstraintSystem<F> for Namespace<'_, F, CS>

§

type Root = <CS as ConstraintSystem<F>>::Root

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

fn one() -> Variable

Return the “one” input variable
source§

fn alloc<FN, A, AR>( &mut self, annotation: A, f: FN ) -> Result<Variable, SynthesisError>where FN: FnOnce() -> Result<F, 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.
source§

fn alloc_input<FN, A, AR>( &mut self, annotation: A, f: FN ) -> Result<Variable, SynthesisError>where FN: FnOnce() -> Result<F, 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.
source§

fn enforce<A, AR, LA, LB, LC>(&mut self, annotation: A, a: LA, b: LB, c: LC)where A: FnOnce() -> AR, AR: AsRef<str>, LA: FnOnce(LinearCombination<F>) -> LinearCombination<F>, LB: FnOnce(LinearCombination<F>) -> LinearCombination<F>, LC: FnOnce(LinearCombination<F>) -> LinearCombination<F>,

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.
source§

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.
source§

fn pop_namespace(&mut self)

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

fn get_root(&mut self) -> &mut Self::Root

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

fn num_constraints(&self) -> usize

Output the number of constraints in the system.
source§

fn num_public_variables(&self) -> usize

Output the number of public input variables to the system.
source§

fn num_private_variables(&self) -> usize

Output the number of private input variables to the system.
source§

fn is_in_setup_mode(&self) -> bool

Output whether the constraint system is in the setup mode.
source§

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.
