Struct light_poseidon::PoseidonParameters

pub struct PoseidonParameters<F: PrimeField> {
    pub ark: Vec<F>,
    pub mds: Vec<Vec<F>>,
    pub full_rounds: usize,
    pub partial_rounds: usize,

    pub alpha: u64,
}

Parameters for the Poseidon hash algorithm.

Fields

ark: Vec<F>

Round constants.

mds: Vec<Vec<F>>

MDS matrix.

full_rounds: usize

Number of full rounds (where S-box is applied to all elements of the state).

partial_rounds: usize

Number of partial rounds (where S-box is applied only to the first element of the state).

width: usize

Number of prime fields in the state.

alpha: u64

Exponential used in S-box to power elements of the state.

Implementations

impl<F: PrimeField> PoseidonParameters<F>

pub fn new( ark: Vec<F>, mds: Vec<Vec<F>>, full_rounds: usize, partial_rounds: usize, width: usize, alpha: u64 ) -> Self
