[−][src]Trait fawkes_crypto_bellman_ce::ConstraintSystem
Represents a constraint system which can have new variables allocated and constrains between them formed.
Associated Types
type Root: ConstraintSystem<E>
Represents the type of the "root" of this constraint system so that nested namespaces can minimize indirection.
Required methods
fn alloc<F, A, AR>(
&mut self,
annotation: A,
f: F
) -> Result<Variable, SynthesisError> where
F: FnOnce() -> Result<E::Fr, SynthesisError>,
A: FnOnce() -> AR,
AR: Into<String>,
&mut self,
annotation: A,
f: F
) -> Result<Variable, SynthesisError> where
F: FnOnce() -> Result<E::Fr, SynthesisError>,
A: FnOnce() -> AR,
AR: Into<String>,
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,
annotation: A,
f: F
) -> Result<Variable, SynthesisError> where
F: FnOnce() -> Result<E::Fr, SynthesisError>,
A: FnOnce() -> AR,
AR: Into<String>,
&mut self,
annotation: A,
f: F
) -> Result<Variable, SynthesisError> where
F: FnOnce() -> Result<E::Fr, SynthesisError>,
A: FnOnce() -> AR,
AR: Into<String>,
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, annotation: A, a: LA, b: LB, c: LC) where
A: FnOnce() -> AR,
AR: Into<String>,
LA: FnOnce(LinearCombination<E>) -> LinearCombination<E>,
LB: FnOnce(LinearCombination<E>) -> LinearCombination<E>,
LC: FnOnce(LinearCombination<E>) -> LinearCombination<E>,
A: FnOnce() -> AR,
AR: Into<String>,
LA: FnOnce(LinearCombination<E>) -> LinearCombination<E>,
LB: FnOnce(LinearCombination<E>) -> LinearCombination<E>,
LC: FnOnce(LinearCombination<E>) -> LinearCombination<E>,
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, name_fn: N) where
NR: Into<String>,
N: FnOnce() -> NR,
NR: Into<String>,
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.
Provided methods
fn one() -> Variable
Return the "one" input variable
fn namespace<'a, NR, N>(
&'a mut self,
name_fn: N
) -> Namespace<'a, E, Self::Root> where
NR: Into<String>,
N: FnOnce() -> NR,
&'a mut self,
name_fn: N
) -> Namespace<'a, E, Self::Root> where
NR: Into<String>,
N: FnOnce() -> NR,
Begin a namespace for this constraint system.
