Struct poseidon_permutation::Instance

pub struct Instance<'a, F: PrimeField> { /* private fields */ }

Represents a generic instance of Poseidon.

Intended for generic fixed-width hashing.

Implementations

impl<'a, F: PrimeField> Instance<'a, F>

pub fn new(parameters: &'a PoseidonParameters<F>) -> Self

Instantiate a new hash function over GF(p) given Parameters.

pub fn n_to_1_fixed_hash(&mut self, input_words: Vec<F>) -> F

Fixed width hash from n:1. Outputs a F given t input words.

pub fn output_words(&self) -> Vec<F>

Print out internal state.

pub fn unoptimized_n_to_1_fixed_hash(&mut self, input_words: Vec<F>) -> F

Fixed width hash from n:1. Outputs a F given t input words. Unoptimized.
