A trait for using commitment schemes generically.

Required Associated Types

type Scalar: Scalar + for<'a> Mul<&'a Self, Output = Self> + Mul<Self, Output = Self> + Serialize + for<'a> Deserialize<'a>

The associated scalar that the commitment is for. There are multiple possible commitment schemes for a scalar, but only one scalar for any commitment.

type PublicSetup

The public setup for the commitment scheme.

Required Methods

fn compute_commitments( commitments: &mut [Self], committable_columns: &[CommittableColumn<'_>], offset: usize, setup: &Self::PublicSetup, )

Compute the commitments for the given columns.

fn fold_commitments(commitments: &[Self], multipliers: &[Self::Scalar]) -> Self

Compute a linear combination of the given commitments: sum commitment[i] * multiplier[i].

Object Safety

This trait is not object safe.
