Implementations§

Source§

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

Source

pub fn setup() -> Self

Initializes a new instance of the cryptographic hash function.

Source

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

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

Source

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.

Source

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.

Source

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