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".

Implementors

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