Trait ark_ff::fields::field_hashers::HashToField

pub trait HashToField<F: Field>: Sized {
    // Required methods
    fn new(domain: &[u8]) -> Self;
    fn hash_to_field(&self, msg: &[u8], count: usize) -> Vec<F>;
}

Trait for hashing messages to field elements.

Required Methods

fn new(domain: &[u8]) -> Self

Initialises a new hash-to-field helper struct.

Arguments

• domain - bytes that get concatenated with the msg during hashing, in order to separate potentially interfering instantiations of the hasher.

fn hash_to_field(&self, msg: &[u8], count: usize) -> Vec<F>

Hash an arbitrary msg to #count elements from field F.

Object Safety

This trait is not object safe.

Implementors

impl<F: Field, H: Default + DynDigest + Clone, const SEC_PARAM: usize> HashToField<F> for DefaultFieldHasher<H, SEC_PARAM>
