Implementations

impl Challenge

pub fn index(&self) -> usize

Index of this challenge.

pub fn phase(&self) -> u8

Phase of this challenge.

pub fn expr<F: Field>(&self) -> Expression<F>

Return Expression

Trait Implementations

impl Clone for Challenge

fn clone(&self) -> Challenge

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Challenge

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

Formats the value using the given formatter.

impl From<Challenge> for ChallengeMid

fn from(val: Challenge) -> Self

Converts to this type from the input type.

impl From<ChallengeMid> for Challenge

fn from(c: ChallengeMid) -> Self

Converts to this type from the input type.

impl Hash for Challenge

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 PartialEq for Challenge

fn eq(&self, other: &Challenge) -> 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.
