Struct Poseidon 

pub struct Poseidon<F: PrimeField, const RATE: usize> { /* private fields */ }

Implementations

impl<F: PrimeField, const RATE: usize> Poseidon<F, RATE>

pub fn setup() -> Self

Initializes a new instance of the cryptographic hash function.

pub fn evaluate(&self, input: &[F]) -> F

Evaluate the cryptographic hash function over a list of field elements as input.

pub fn evaluate_many(&self, input: &[F], num_outputs: usize) -> Vec<F>

Evaluate the cryptographic hash function over a list of field elements as input, and returns the specified number of field elements as output.

pub fn evaluate_with_len(&self, input: &[F]) -> F

Evaluate the cryptographic hash function over a non-fixed-length vector, in which the length also needs to be hashed.

pub fn parameters(&self) -> &Arc<PoseidonParameters<F, RATE, 1>>

Trait Implementations

impl<F: Clone + PrimeField, const RATE: usize> Clone for Poseidon<F, RATE>

fn clone(&self) -> Poseidon<F, RATE>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<F: Debug + PrimeField, const RATE: usize> Debug for Poseidon<F, RATE>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<F: PartialEq + PrimeField, const RATE: usize> PartialEq for Poseidon<F, RATE>

fn eq(&self, other: &Poseidon<F, RATE>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
