Struct RescuePermutation

pub struct RescuePermutation<F: RescueParameter, const R: usize> { /* private fields */ }

State of rescue sponge, containing necessary permutation instance. Replacing RescueSponge, see module doc.

Trait Implementations

impl<F: RescueParameter, const R: usize> AsMut<[F]> for RescuePermutation<F, R>

fn as_mut(&mut self) -> &mut [F]

Converts this type into a mutable reference of the (usually inferred) input type.

impl<F: RescueParameter, const R: usize> AsRef<[F]> for RescuePermutation<F, R>

fn as_ref(&self) -> &[F]

Converts this type into a shared reference of the (usually inferred) input type.

impl<F: Clone + RescueParameter, const R: usize> Clone for RescuePermutation<F, R>

fn clone(&self) -> RescuePermutation<F, R>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<F: RescueParameter, const R: usize> Debug for RescuePermutation<F, R>

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

Formats the value using the given formatter.

impl<F: Default + RescueParameter, const R: usize> Default for RescuePermutation<F, R>

fn default() -> RescuePermutation<F, R>

Returns the “default value” for a type.

impl<F: RescueParameter, const R: usize> Permutation for RescuePermutation<F, R>

const N: usize = 4usize

The width of the sponge, equal to rate [Permutation::R] plus capacity. Cannot be less than 1. Cannot be less than [Permutation::R].

const R: usize = R

The rate of the sponge.

type U = F

The basic unit over which the sponge operates.

fn new(iv: [u8; 32]) -> Self

Initialize the state of the sponge using 32 bytes of seed.

fn permute(&mut self)

Permute the state of the sponge.

impl<F: RescueParameter, const R: usize> Zeroize for RescuePermutation<F, R>

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
