Struct winter_prover::ConstraintCommitment

pub struct ConstraintCommitment<E: FieldElement, H: ElementHasher<BaseField = E::BaseField>> { /* private fields */ }

Expand description

Constraint evaluation commitment.

The commitment consists of two components:

Evaluations of composition polynomial columns over the LDE domain.
Merkle tree where each leaf in the tree corresponds to a row in the composition polynomial evaluation matrix.

Implementations§

impl<E: FieldElement, H: ElementHasher<BaseField = E::BaseField>> ConstraintCommitment<E, H>

pub fn new( evaluations: RowMatrix<E>, commitment: MerkleTree<H> ) -> ConstraintCommitment<E, H>

Creates a new constraint evaluation commitment from the provided composition polynomial evaluations and the corresponding Merkle tree commitment.

pub fn root(&self) -> H::Digest

Returns the root of the commitment Merkle tree.

pub fn tree_depth(&self) -> usize

Returns the depth of the commitment Merkle tree.

pub fn query(self, positions: &[usize]) -> Queries

Returns constraint evaluations at the specified positions along with Merkle authentication paths from the root of the commitment to these evaluations.
