Arithmetic computation supported by fancy garbling.

id represents the gate number. out gives the output wire index; if out = None, then we use the gate index as the output wire index.

Trait Implementations

impl Clone for ArithmeticGate

fn clone(&self) -> ArithmeticGate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ArithmeticGate

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ArithmeticGate

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ArithmeticGate

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

Formats the value using the given formatter.

impl GateType for ArithmeticGate

fn make_constant(val: u16) -> Self

Generate constant gate

fn make_garbler_input(id: usize) -> Self

Generate garbler input gate

fn make_evaluator_input(id: usize) -> Self

Generate evaluator input gate

impl PartialEq for ArithmeticGate

fn eq(&self, other: &ArithmeticGate) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ArithmeticGate

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
