Struct Challenge

pub struct Challenge(/* private fields */);

Natural extension of the Curve Point to the Proof-of-Relay challenge. Proof-of-Relay challenge is a secp256k1 curve point.

Implementations

impl Challenge

pub fn to_ethereum_challenge(&self) -> EthereumChallenge

Converts the PoR challenge to an Ethereum challenge. This is a one-way (lossy) operation, since the corresponding curve point is hashed with the hash value then truncated.

impl Challenge

pub fn from_hint_and_share( own_share: &HalfKeyChallenge, hint: &HalfKeyChallenge, ) -> Result<Self>

Gets the PoR challenge by adding the two EC points represented by the half-key challenges

pub fn from_own_share_and_half_key( own_share: &HalfKeyChallenge, half_key: &HalfKey, ) -> Result<Self>

Gets the PoR challenge by converting the given HalfKey into a secp256k1 point and adding it with the given HalfKeyChallenge (which already represents a secp256k1 point).

Trait Implementations

impl AsRef<[u8]> for Challenge

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl BytesRepresentable for Challenge

const SIZE: usize = 33usize

Size of the encoded byte array.

fn into_boxed(self) -> Box<[u8]>

Convenience function to copy this type’s binary representation into a Box.

impl Clone for Challenge

fn clone(&self) -> Challenge

Returns a duplicate 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 EthereumChallenge

fn from(challenge: Challenge) -> Self

Converts to this type from the input type.

impl From<CurvePoint> for Challenge

fn from(curve_point: CurvePoint) -> Self

Converts to this type from the input type.

impl From<Response> for Challenge

fn from(response: Response) -> Self

Converts to this type from the input type.

impl PartialEq for Challenge

fn eq(&self, other: &Challenge) -> 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 TryFrom<&[u8]> for Challenge

type Error = GeneralError

The type returned in the event of a conversion error.

fn try_from(value: &[u8]) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for Challenge

impl StructuralPartialEq for Challenge
