Trait neptune::BatchHasher

pub trait BatchHasher<F, A>
where
    F: PrimeField,
    A: Arity<F>,
{
    // Required method
    fn hash(
        &mut self,
        preimages: &[GenericArray<F, A>],

    fn max_batch_size(&self) -> usize { ... }
}

Required Methods

fn hash(&mut self, preimages: &[GenericArray<F, A>]) -> Result<Vec<F>, Error>

Provided Methods

fn hash_into_slice( &mut self, target_slice: &mut [F], preimages: &[GenericArray<F, A>], ) -> Result<(), Error>

fn max_batch_size(&self) -> usize

max_batch_size is advisory. Implenters of BatchHasher should ensure that up to the returned max hashes can be safely performed on the target GPU (currently 2080Ti). The max returned should represent a safe batch size optimized for performance. BatchHasher users are responsible for not attempting to hash batches larger than the advised maximum.
