Trait HashToField

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

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<const N: usize>(&self, msg: &[u8]) -> [F; N]

Hash an arbitrary msg to N elements of the field F.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

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