Struct Pow

pub struct Pow<T> { /* private fields */ }

Proof of work over concrete type T. T can be any type that implements serde::Serialize.

Implementations

impl<T: Serialize> Pow<T>

pub fn prove_work(t: &T, difficulty: u128) -> Result<Pow<T>>

Prove work over T.

Make sure difficulty is not too high. A 64 bit difficulty, for example, takes a long time on a general purpose processor.

Returns bincode::Error if serialization fails.

pub fn prove_work_serialized(prefix: &[u8], difficulty: u128) -> Pow<T>

Prove work on an already serialized item of type T. The input is assumed to be serialized using network byte order.

Make sure difficulty is not too high. A 64 bit difficulty, for example, takes a long time on a general purpose processor.

pub fn score(&self, t: &T) -> Result<u128>

Calculate the pow score of t and self.

pub fn score_serialized(&self, target: &[u8]) -> u128

Calculate the pow score of an already serialized T and self. The input is assumed to be serialized using network byte order.

Trait Implementations

impl<T: Clone> Clone for Pow<T>

fn clone(&self) -> Pow<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Pow<T>

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

Formats the value using the given formatter.

impl<'de, T> Deserialize<'de> for Pow<T>

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T: PartialEq> PartialEq for Pow<T>

fn eq(&self, other: &Pow<T>) -> 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<T> Serialize for Pow<T>

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<T: Copy> Copy for Pow<T>
