Struct Instance

pub struct Instance<'a, const STATE_SIZE: usize, const STATE_SIZE_MINUS_1: usize, const NUM_MDS_ELEMENTS: usize, const NUM_STATE_SIZE_MINUS_1_ELEMENTS: usize, const NUM_ROUND_ROWS: usize, const NUM_ROUND_COLS: usize, const NUM_ROUND_ELEMENTS: usize, const NUM_PARTIAL_ROUNDS: usize> { /* private fields */ }

Represents a generic instance of Poseidon.

Intended for generic fixed-width hashing.

pub fn new( parameters: &'a PoseidonParameters<STATE_SIZE, STATE_SIZE_MINUS_1, NUM_MDS_ELEMENTS, NUM_STATE_SIZE_MINUS_1_ELEMENTS, NUM_ROUND_ROWS, NUM_ROUND_COLS, NUM_ROUND_ELEMENTS, NUM_PARTIAL_ROUNDS>, ) -> Self

Instantiate a new hash function over Fq given Parameters.

pub fn n_to_1_fixed_hash(&mut self, input_words: &[Fq; STATE_SIZE]) -> Fq

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

pub fn output_words(&self) -> [Fq; STATE_SIZE]

Print out internal state.

pub fn unoptimized_n_to_1_fixed_hash( &mut self, input_words: [Fq; STATE_SIZE], ) -> Fq

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