Implementations

impl<FA, ExternalPerm, InternalPerm, const WIDTH: usize, const D: u64> Poseidon2<FA, ExternalPerm, InternalPerm, WIDTH, D>

where FA: FieldAlgebra, <FA as FieldAlgebra>::F: PrimeField, ExternalPerm: ExternalLayerConstructor<FA, WIDTH>, InternalPerm: InternalLayerConstructor<FA>,

pub fn new( external_constants: ExternalLayerConstants<<FA as FieldAlgebra>::F, WIDTH>, internal_constants: Vec<<FA as FieldAlgebra>::F>, ) -> Poseidon2<FA, ExternalPerm, InternalPerm, WIDTH, D>

Create a new Poseidon2 configuration. This internally converts the given constants to the relevant packed versions.

pub fn new_from_rng<R>( rounds_f: usize, rounds_p: usize, rng: &mut R, ) -> Poseidon2<FA, ExternalPerm, InternalPerm, WIDTH, D>

where R: Rng, Standard: Distribution<<FA as FieldAlgebra>::F> + Distribution<[<FA as FieldAlgebra>::F; WIDTH]>,

Create a new Poseidon2 configuration with random parameters.

impl<FA, ExternalPerm, InternalPerm, const WIDTH: usize, const D: u64> Poseidon2<FA, ExternalPerm, InternalPerm, WIDTH, D>

where FA: FieldAlgebra, <FA as FieldAlgebra>::F: PrimeField64, ExternalPerm: ExternalLayerConstructor<FA, WIDTH>, InternalPerm: InternalLayerConstructor<FA>,

pub fn new_from_rng_128<R>( rng: &mut R, ) -> Poseidon2<FA, ExternalPerm, InternalPerm, WIDTH, D>

where R: Rng, Standard: Distribution<<FA as FieldAlgebra>::F> + Distribution<[<FA as FieldAlgebra>::F; WIDTH]>,

Create a new Poseidon2 configuration with 128 bit security and random rounds constants.
