Trait HashToScalar

pub trait HashToScalar {

    // Required method
    fn hash_to_scalar(
        &self,
        input: &[Self::Input],
    ) -> Result<Self::Output, Error>;
}

A trait for a hash function that projects the value to a scalar.

Required Methods

fn hash_to_scalar(&self, input: &[Self::Input]) -> Result<Self::Output, Error>

Returns the hash of the given input.

Implementations on Foreign Types

impl<E, const RATE: usize> HashToScalar for Poseidon<E, RATE>

where E: Environment,

fn hash_to_scalar( &self, input: &[<Poseidon<E, RATE> as HashToScalar>::Input], ) -> Result<<Poseidon<E, RATE> as HashToScalar>::Output, Error>

Returns a scalar from hashing the input. This method uses truncation (up to data bits) to project onto the scalar field.

type Input = Field<E>

type Output = Scalar<E>
