[][src]Struct neptune::poseidon::Poseidon

pub struct Poseidon<'a, E, A = U2> where
    E: ScalarEngine,
    A: Arity<E::Fr>, 
{ pub elements: GenericArray<E::Fr, A::ConstantsSize>, // some fields omitted }

The Poseidon structure will accept a number of inputs equal to the arity.

Fields

elements: GenericArray<E::Fr, A::ConstantsSize>

the elements to permute

Implementations

impl<'a, E, A> Poseidon<'a, E, A> where
    E: ScalarEngine,
    A: Arity<E::Fr>, 
[src]

pub fn new(constants: &'a PoseidonConstants<E, A>) -> Self[src]

pub fn new_with_preimage(
    preimage: &[E::Fr],
    constants: &'a PoseidonConstants<E, A>
) -> Self
[src]

pub fn set_preimage(&mut self, preimage: &[E::Fr])[src]

Replace the elements with the provided optional items.

Panics

Panics if the provided slice is bigger than the arity.

pub fn reset(&mut self)[src]

Restore the initial state

pub fn input(&mut self, element: E::Fr) -> Result<usize, Error>[src]

The returned usize represents the element position (within arity) for the input operation

pub fn hash_in_mode(&mut self, mode: HashMode) -> E::Fr[src]

pub fn hash(&mut self) -> E::Fr[src]

pub fn hash_optimized_static(&mut self) -> E::Fr[src]
