Struct HashVarlen

pub struct HashVarlen;

Calculate hash of a raw sequence of a BFieldElement.

Implementations

impl HashVarlen

pub fn sponge_mutation(&self, sponge: &mut VmHasher, preimage: &[BFieldElement])

Mutate the sponge with the same operations as this snippet Used to facilitate rust-shadowing in downstream dependencies.
