Struct HashConfig 

pub struct HashConfig {
    pub salt: u64,
    /* private fields */
}

Configuration for the hashing system.

Contains the modulus used for finite field arithmetic. The default is a 61-bit Mersenne prime.

Fields

salt: u64

Prime modulus used for all field operations.

Implementations

impl HashConfig

pub fn _hash<const K: usize>(self, s: &Vec<u64>) -> [u64; 5]

Internal generic hash function.

Computes a polynomial fingerprint of the input using K evaluation points.

Note

Returns raw byte representation of field outputs.

pub fn hash122(self, s: &Vec<u64>) -> Vec<u8>

122-bit hash (K = 2 evaluations & very small entropy for real usage)

pub fn hash183(self, s: &Vec<u64>) -> Vec<u8>

183-bit hash (K = 3 evaluations & recommended using for better performance)

pub fn hash244(self, s: &Vec<u64>) -> Vec<u8>

244-bit hash (K = 4 evaluations & recommended for most usages)

pub fn hash305(self, s: &Vec<u64>) -> Vec<u8>

305-bit hash (K = 5 evaluations & not recommended for most usages)

pub fn new(salt: u64) -> HashConfig

Creates a new hash configuration using a 61-bit Mersenne prime field.

Trait Implementations

impl Clone for HashConfig

fn clone(&self) -> HashConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.
