Trait neptune::BatchHasher[−][src]

pub trait BatchHasher<A> where
    A: Arity<Scalar>, {
    fn hash(
        &mut self, 
        preimages: &[GenericArray<Scalar, A>]
    ) -> Result<Vec<Scalar>, Error>;

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

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

Required methods

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

Provided methods

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

fn max_batch_size(&self) -> usize[src]

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.
