Struct HalfKey

pub struct HalfKey { /* private fields */ }

Represents a half-key used for the Proof-of-Relay.

Half-key is equivalent to a non-zero scalar in the field used by secp256k1, but the type itself does not validate nor enforce this fact.

Implementations

impl HalfKey

pub fn random() -> Self

Generates random half-key, useful for tests.

pub fn to_challenge(&self) -> HalfKeyChallenge

Converts the non-zero scalar represented by this half-key into the half-key challenge. This operation naturally enforces the underlying scalar to be non-zero.

Trait Implementations

impl AsRef<[u8]> for HalfKey

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

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

impl BytesRepresentable for HalfKey

const SIZE: usize = 32usize

Size of the secp256k1 secret scalar representing the half key.

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

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

impl Clone for HalfKey

fn clone(&self) -> HalfKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HalfKey

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

Formats the value using the given formatter.

impl Default for HalfKey

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for HalfKey

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<HalfKey> for HalfKeyChallenge

fn from(half_key: HalfKey) -> Self

Converts to this type from the input type.

impl PartialEq for HalfKey

fn eq(&self, other: &HalfKey) -> 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 HalfKey

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&[u8]> for HalfKey

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 Copy for HalfKey

impl Eq for HalfKey
