Trait Implementations

impl<F: Clone + Field, SC: Clone + SpongeConstants, const FULL_ROUNDS: usize> Clone for ArithmeticSponge<F, SC, FULL_ROUNDS>

fn clone(&self) -> ArithmeticSponge<F, SC, FULL_ROUNDS>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<F: Field, SC: SpongeConstants, const FULL_ROUNDS: usize> Sponge<F, F, FULL_ROUNDS> for ArithmeticSponge<F, SC, FULL_ROUNDS>

fn absorb(&mut self, x: &[F])

Absorb an array of field elements x into the sponge.

Security

WARNING: This function produces collisions when inputs differ only in trailing zeros until reaching an even length input. Therefore, use only with inputs of fixed-length.

fn new(params: &'static ArithmeticSpongeParams<F, FULL_ROUNDS>) -> Self

Create a new cryptographic sponge using arithmetic sponge params

fn squeeze(&mut self) -> F

Squeeze an output from the sponge

fn reset(&mut self)

Reset the sponge back to its initial state (as if it were just created)
