Struct PovwNonce 

pub struct PovwNonce {
    pub log: PovwLogId,
    pub job: u64,
    pub segment: u32,
}

A 256-bit unique nonce for Proof of Verifiable Work.

Each nonce uniquely identifies a single segment proof and prevents double-counting of work. The nonce has a structured format combining a work log ID, job number, and segment index.

Fields

log: PovwLogId

Work log identifier.

job: u64

Job number within the work log.

segment: u32

Segment index within the job.

Implementations

impl PovwNonce

pub const ZERO: Self

impl Debug for PovwNonce

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

Formats the value using the given formatter.

impl Default for PovwNonce

fn default() -> PovwNonce

Returns the “default value” for a type.

impl Distribution<PovwNonce> for StandardUniform

Available on crate feature rand only.

fn sample<R: Rng + ?Sized>(&self, rng: &mut R) -> PovwNonce

Generate a random value of T, using rng as the source of randomness.

fn sample_iter<R>(self, rng: R) -> Iter<Self, R, T>

where R: Rng, Self: Sized,

Create an iterator that generates random values of T, using rng as the source of randomness.

fn map<F, S>(self, func: F) -> Map<Self, F, T, S>

where F: Fn(T) -> S, Self: Sized,

impl From<PovwNonce> for U256

fn from(value: PovwNonce) -> Self

Convert a PovwNonce to its U256 representation.

impl From<Uint<256, 4>> for PovwNonce

fn from(value: U256) -> Self

Convert a U256 to a PovwNonce.

All U256 can be mapped to a unique PoVW nonce.

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