Trait Implementations

impl PoseidonParams<Fp<BLS12Param, { usize::div_ceil( $bits, $crate::arithmetic::limb::Limb::BITS as usize, ) }>> for BLS4Params

const T: usize = 4usize

State size.

const D: u8 = 5u8

Number of full rounds.

const ROUNDS_P: usize = 56usize

Number of partial rounds.

const MAT_INTERNAL_DIAG_M_1: &'static [FpBLS12]

MDS (Maximum Distance Separable) matrix used in the Poseidon permutation.

const ROUND_CONSTANTS: &'static [&'static [FpBLS12]]

The round constants used in the full and partial rounds of the Poseidon permutation.
