Struct pow_sha256::PoW

pub struct PoW<T> {
    pub nonce: u64,
    pub result: String,
    // some fields omitted
}

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

Fields

nonce: u64

result: String

Methods

impl<T: Serialize> PoW<T>

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

Create Proof of Work over item of type 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>

Create Proof of 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 calculate(&self, t: &T) -> Result<u128>

Calculate the PoW score with the provided input T.

pub fn calculate_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.

pub fn is_valid_proof(&self, t: &T) -> bool

Verifies that the PoW is indeed generated out of the phrase provided.

pub fn is_sufficient_difficulty(&self, target_diff: u128) -> bool

Checks if the PoW result is of sufficient difficulty

Trait Implementations
