Struct snarkvm_algorithms::r1cs::Variable

pub struct Variable(_);

Represents a variable in a constraint system.

Implementations

impl Variable

pub fn new_unchecked(idx: Index) -> Variable

This constructs a variable with an arbitrary index. Circuit implementations are not recommended to use this.

pub fn get_unchecked(&self) -> Index

This returns the index underlying the variable. Circuit implementations are not recommended to use this.

Trait Implementations

impl<F: Field> Add<Variable> for ConstraintVariable<F>

type Output = ConstraintVariable<F>

The resulting type after applying the + operator.

fn add(self, other: Variable) -> Self

Performs the + operation.

impl<F: Field> Add<Variable> for LinearCombination<F>

type Output = LinearCombination<F>

The resulting type after applying the + operator.

fn add(self, other: Variable) -> LinearCombination<F>

Performs the + operation.

impl Clone for Variable

fn clone(&self) -> Variable

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Variable

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

Formats the value using the given formatter.

impl<F: Field> From<Variable> for ConstraintVariable<F>

fn from(var: Variable) -> Self

Converts to this type from the input type.

impl<F: Field> From<Variable> for LinearCombination<F>

fn from(var: Variable) -> Self

Converts to this type from the input type.

impl Hash for Variable

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Variable

fn cmp(&self, other: &Variable) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Variable> for Variable

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd<Variable> for Variable

fn partial_cmp(&self, other: &Variable) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl<F: Field> Sub<Variable> for ConstraintVariable<F>

type Output = ConstraintVariable<F>

The resulting type after applying the - operator.

fn sub(self, other: Variable) -> Self

Performs the - operation.

impl<F: Field> Sub<Variable> for LinearCombination<F>

type Output = LinearCombination<F>

The resulting type after applying the - operator.

fn sub(self, other: Variable) -> LinearCombination<F>

Performs the - operation.
