[src]
pub fn get_variable(&self) -> Variable
[src]
pub fn alloc_conditionally<E, CS>(

[src]
cs: CS,
value: Option<bool>,
must_be_false: &AllocatedBit
) -> Result<Self, SynthesisError> where
E: ScalarEngine,
CS: ConstraintSystem<E>,
Allocate a variable in the constraint system which can only be a boolean value. Further, constrain that the boolean is false unless the condition is false.
pub fn alloc<E, CS>(cs: CS, value: Option<bool>) -> Result<Self, SynthesisError> where
E: ScalarEngine,
CS: ConstraintSystem<E>,
[src]
E: ScalarEngine,
CS: ConstraintSystem<E>,
Allocate a variable in the constraint system which can only be a boolean value.
pub fn xor<E, CS>(cs: CS, a: &Self, b: &Self) -> Result<Self, SynthesisError> where
E: ScalarEngine,
CS: ConstraintSystem<E>,
[src]
E: ScalarEngine,
CS: ConstraintSystem<E>,
Performs an XOR operation over the two operands, returning
an AllocatedBit
.
pub fn and<E, CS>(cs: CS, a: &Self, b: &Self) -> Result<Self, SynthesisError> where
E: ScalarEngine,
CS: ConstraintSystem<E>,
[src]
E: ScalarEngine,
CS: ConstraintSystem<E>,
Performs an AND operation over the two operands, returning
an AllocatedBit
.
pub fn and_not<E, CS>(
cs: CS,
a: &Self,
b: &Self
) -> Result<Self, SynthesisError> where
E: ScalarEngine,
CS: ConstraintSystem<E>,
[src]
cs: CS,

b: &Self
) -> Result<Self, SynthesisError> where
E: ScalarEngine,
CS: ConstraintSystem<E>,
Calculates a AND (NOT b)
.
pub fn nor<E, CS>(cs: CS, a: &Self, b: &Self) -> Result<Self, SynthesisError> where
E: ScalarEngine,
CS: ConstraintSystem<E>,
[src]
E: ScalarEngine,
CS: ConstraintSystem<E>,
Calculates (NOT a) AND (NOT b)
.
