Struct ark_poly_commit::ipa_pc::Commitment

pub struct Commitment<G: AffineCurve> {
    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.

Trait Implementations

impl<G: AffineCurve> CanonicalDeserialize for Commitment<G>

fn deserialize<R: Read>(reader: R) -> Result<Self, SerializationError>

Reads Self from reader.

fn deserialize_uncompressed<R: Read>(
    reader: R
) -> Result<Self, SerializationError>

Reads Self from reader without compression.

fn deserialize_unchecked<R: Read>(reader: R) -> Result<Self, SerializationError>

Reads self from reader without compression, and without performing validity checks. Should be used only when the input is trusted.

impl<G: AffineCurve> CanonicalSerialize for Commitment<G>

fn serialize<W: Write>(&self, writer: W) -> Result<(), SerializationError>

Serializes self into writer. It is left up to a particular type for how it strikes the serialization efficiency vs compression tradeoff. For standard types (e.g. bool, lengths, etc.) typically an uncompressed form is used, whereas for algebraic types compressed forms are used.

fn serialized_size(&self) -> usize

fn serialize_uncompressed<W: Write>(
    &self,
    writer: W
) -> Result<(), SerializationError>

Serializes self into writer without compression.

fn serialize_unchecked<W: Write>(
    &self,
    writer: W
) -> Result<(), SerializationError>

Serializes self into writer without compression, and without performing validity checks. Should be used only when there is no danger of adversarial manipulation of the output.

fn uncompressed_size(&self) -> usize

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

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

Formats the value using the given formatter.

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

fn default() -> Self

Returns the “default value” for a type.

impl<G: AffineCurve> 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, 

Feeds a slice of this type into the given Hasher.

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

fn empty() -> Self

Outputs a non-hiding commitment to the zero polynomial.

fn has_degree_bound(&self) -> bool

Does this commitment have a degree bound?

fn size_in_bytes(&self) -> usize

Size in bytes

impl<G: AffineCurve> PCPreparedCommitment<Commitment<G>> for PreparedCommitment<G>

fn prepare(vk: &Commitment<G>) -> Self

prepare PreparedCommitment from Commitment

impl<G: AffineCurve> PartialEq<Commitment<G>> for Commitment<G>

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl<G: AffineCurve> ToBytes for Commitment<G>

fn write<W: Write>(&self, writer: W) -> Result<()>

Serializes self into writer.

impl<G: AffineCurve> Copy for Commitment<G>

impl<G: AffineCurve> Eq for Commitment<G>
