Struct Commitment

pub struct Commitment<G: AffineRepr> {
    pub comm: G,
    pub shifted_comm: Option<G>,
}

Commitment to a polynomial that optionally enforces a degree bound.

Fields

comm: G

A Pedersen commitment to the polynomial.

shifted_comm: Option<G>

A Pedersen commitment to the shifted polynomial. This is none if the committed polynomial does not enforce a strict degree bound.

impl<G: AffineRepr> Clone for Commitment<G>

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<G: AffineRepr> Debug for Commitment<G>

fn fmt(&self, __f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<G: AffineRepr> Default for Commitment<G>

fn default() -> Self

Returns the “default value” for a type.

impl<G: AffineRepr> Hash for Commitment<G>

fn hash<__HG>(&self, __state: &mut __HG)

where __HG: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<G: AffineRepr> PCCommitment for Commitment<G>

fn empty() -> Self

Outputs a non-hiding commitment to the zero polynomial.
