Implementations

impl Witness

pub fn new(witness_index: u32) -> Witness

pub fn witness_index(&self) -> u32

pub fn as_usize(&self) -> usize

Trait Implementations

impl<F: AcirField> Add<&Expression<F>> for Witness

type Output = Expression<F>

The resulting type after applying the + operator.

fn add(self, rhs: &Expression<F>) -> Self::Output

Performs the + operation.

impl<F: AcirField> Add<Witness> for &Expression<F>

type Output = Expression<F>

The resulting type after applying the + operator.

fn add(self, rhs: Witness) -> Self::Output

Performs the + operation.

impl Clone for Witness

fn clone(&self) -> Witness

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Witness

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

Formats the value using the given formatter.

impl Default for Witness

fn default() -> Witness

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Witness

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Witness

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

Formats the value using the given formatter.

impl<F: AcirField> From<Witness> for Expression<F>

fn from(wit: Witness) -> Self

Creates an Expression from a Witness.

This is infallible since an Expression is a multi-variate polynomial and a Witness can be seen as a univariate polynomial

impl From<u32> for Witness

fn from(value: u32) -> Self

Converts to this type from the input type.

impl Hash for Witness

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<F> Index<&Witness> for WitnessMap<F>

type Output = F

The returned type after indexing.

fn index(&self, index: &Witness) -> &Self::Output

Performs the indexing (container[index]) operation.

impl MsgpackTagged for Witness

where u32: MsgpackTagged,

const TAGGED: Tagged

The wire shape of this type — either a Product (struct/tuple struct) or a Sum (enum). The derive macro emits this from #[tag(N)] annotations; primitives and container types use a Tagged::Product with empty fields, signalling they don’t appear directly on the wire as a registry entry but still satisfy the bound.

fn register_into(_reg: &mut TagRegistry)

Recursively register this type and every tagged field type into a registry.

impl Ord for Witness

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Witness

fn eq(&self, other: &Witness) -> 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 PartialOrd for Witness

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for Witness

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<F: AcirField> Sub<&Expression<F>> for Witness

type Output = Expression<F>

The resulting type after applying the - operator.

fn sub(self, rhs: &Expression<F>) -> Self::Output

Performs the - operation.

impl<F: AcirField> Sub<Witness> for &Expression<F>

type Output = Expression<F>

The resulting type after applying the - operator.

fn sub(self, rhs: Witness) -> Self::Output

Performs the - operation.
